AP130-28YG-13 Equivalent & Substitute Parts

Part Overview

The AP130-28YG-13 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 2.8V output at 300mA with a maximum dropout voltage of 0.5V, housed in a SOT-89-3 surface mount package. The part is currently active in production with 5400 units in stock.

Substitute parts are necessary when the primary part becomes unavailable due to supply constraints, discontinuation, or packaging format requirements. The AP130 series provides multiple equivalent options across different packaging configurations while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the AP130-28YG-13 is determined by the following criteria:

Electrical Parameters (Must Match):

Output voltage: 2.8V fixed
Output current capability: 300mA
Input voltage maximum: 5.5V
Dropout voltage: 0.5V @ 300mA
Quiescent current: 100 µA
PSRR: 58dB (100Hz)
Operating temperature range: -40°C to 85°C
Protection features: Over Current, Over Temperature, Short Circuit

Mechanical Parameters (Must Match):

Engineering Selection Recommendations

Primary Selection: AP130-28YG-13 This part is the recommended choice for new designs. It is currently active in production with the highest inventory availability (5400 units) and is packaged in Tape & Reel format, suitable for automated assembly processes.

Secondary Selection: AP130-28YRL-13 This part is electrically and mechanically identical to the primary part. It differs only in the supplier device package designation (SOT-89R-3 vs. SOT-89-3) and packaging format (Cut Tape vs. Tape & Reel). This part is active in production with 3700 units in stock. Select this part when Cut Tape packaging is required or when Tape & Reel format is unavailable.

Tertiary Selection: AP130-28YL-13 This part is electrically and mechanically equivalent but is discontinued at DiGi Electronics. It should be selected only when the primary and secondary options are unavailable and existing inventory can be sourced through alternative channels. Inventory availability is limited to 2440 units.

All three parts are ROHS3 compliant and carry identical protection features and performance specifications. Selection should be based on product status, packaging format requirements, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can AP130-28YRL-13 be used as a direct replacement for AP130-28YG-13? A: Yes. Both parts are electrically and mechanically identical. The only differences are the supplier device package designation (SOT-89R-3 vs. SOT-89-3) and packaging format (Cut Tape vs. Tape & Reel). Both packages are physically compatible with the same PCB footprint.

Q: What is the difference between SOT-89-3 and SOT-89R-3 packages? A: Both designations refer to the same physical package case (TO-243AA) with identical pin configuration and dimensions. The "R" designation in SOT-89R-3 indicates a reel-compatible variant. Both are surface mount packages with three leads.

Q: Why is AP130-28YL-13 marked as discontinued? A: AP130-28YL-13 is discontinued at DiGi Electronics but remains electrically and mechanically equivalent to the active parts. It should only be selected when primary and secondary options are unavailable.

Q: Are there any electrical performance differences between the three parts? A: No. All three parts deliver identical electrical performance: 2.8V fixed output, 300mA output current, 0.5V maximum dropout voltage, 100 µA quiescent current, and 58dB PSRR at 100Hz.

Q: What packaging formats are available? A: AP130-28YG-13 is supplied in Tape & Reel (TR) format. AP130-28YRL-13 is supplied in Cut Tape (CT) format. Both formats are suitable for surface mount assembly; selection depends on production volume and equipment compatibility.

Q: Are all parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
