AN8005 Linear Voltage Regulator - Equivalent & Substitute Parts

Part Overview

The AN8005 is a linear voltage regulator IC manufactured by Panasonic Electronic Components, designed to provide a fixed 5V positive output at 50mA. This device is classified as a Power Management (PMIC) component and features a Through Hole mounting type in a TO-226-3/TO-92-3 package configuration. The AN8005 is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AN8005 are identified based on the following critical parameters that determine functional compatibility:

• Output voltage configuration: Fixed positive 5V output
• Output current capability: Minimum 50mA required
• Package type: TO-92-3 / TO-226-3 Through Hole configuration
• Input voltage tolerance: Maximum input voltage rating must accommodate system supply
• Protection features: Over current protection as baseline requirement
• Mounting compatibility: Through Hole pin configuration

The TL750L05CLP from Texas Instruments qualifies as a substitute based on these criteria. It maintains the same fixed 5V positive output, operates in the same TO-92-3 package, and provides enhanced current output capability (150mA) and additional protection features while maintaining Through Hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TL750L05CLP is a direct functional substitute for the AN8005 in applications requiring a fixed 5V positive linear regulator in TO-92-3 Through Hole packaging. The substitute part maintains electrical compatibility with identical output voltage and exceeds the minimum current output requirement of the original part.

The TL750L05CLP offers the advantage of active product status, ensuring continued availability and supply chain reliability. The device is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The enhanced protection feature set (Over Temperature, Over Voltage, and Reverse Polarity protection in addition to Over Current) provides improved system robustness compared to the original AN8005.

The operating temperature range of the substitute part (0°C ~ 125°C) is narrower at the lower end compared to the AN8005 (-30°C ~ 125°C). Applications requiring operation below 0°C must account for this limitation.

Frequently Asked Questions (FAQ)

Q: Can the TL750L05CLP directly replace the AN8005 in existing designs?

A: Yes, the TL750L05CLP is a direct pin-compatible substitute. Both devices use the TO-92-3 package with identical pinout and Through Hole mounting. The substitute part provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Current output capability—TL750L05CLP provides 150mA versus 50mA for the AN8005; (2) Protection features—TL750L05CLP includes Over Temperature, Over Voltage, and Reverse Polarity protection in addition to Over Current; (3) Product status—TL750L05CLP is active while AN8005 is obsolete; (4) Operating temperature minimum—TL750L05CLP operates from 0°C while AN8005 operates from -30°C.

Q: Are there any compatibility concerns with the package?

A: No. Both parts use identical TO-92-3 / TO-226-3 Through Hole packaging. Pin configuration and mechanical dimensions are compatible, allowing direct board-level substitution without layout modifications.

Q: Does the higher current rating of the substitute part affect circuit operation?

A: No. The higher current rating (150mA) of the TL750L05CLP is a capability enhancement. If the original design draws 50mA or less, the substitute part will operate identically. The higher rating provides design margin and supports potential future current demand increases.

Q: What is the significance of the additional protection features in the substitute part?

A: The TL750L05CLP includes Over Temperature, Over Voltage, and Reverse Polarity protection beyond the Over Current protection of the AN8005. These features enhance system reliability by protecting against fault conditions, though they do not affect normal operation in properly designed circuits.

Q: Is the operating temperature range difference a concern?

A: The TL750L05CLP operates from 0°C to 125°C, while the AN8005 operates from -30°C to 125°C. If your application requires operation below 0°C, the substitute part is not suitable. For standard industrial and commercial temperature ranges (0°C and above), the substitute part is fully compatible.
