Product details

Overview

AP130-25YG-13 from Diodes Incorporated is a fixed 2.5V, 300mA low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates PMOS pass element, thermal shutdown, and current-limit protection, and is designed for battery-powered peripherals requiring stable low-noise supply.

For engineers reviewing the AP130-25YG-13 datasheet, AP130-25YG-13 pinout, AP130-25YG-13 application, or AP130-25YG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θ_JA = 100°C/W), green RoHS-compliant packaging, and compatibility with 10µF output capacitance for stability.

Technical Context

The AP130-25YG-13 uses a PMOS pass transistor with 1.5Ω R_ON, eliminating base drive current and enabling ultra-low quiescent current across load range. Its bandgap reference and error amplifier deliver tight load regulation (±40mV) and line regulation (±0.3%/V) over input 2.7–5.5V.

Internal short-circuit fold-back limits peak fault current to 150–300mA while thermal shutdown activates at T_J ≥ 125°C. PSRR reaches 58dB at 100Hz with 1µF/10µF input/output capacitors, supporting noise-sensitive analog and RF subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.5V ±2% - ensures precise biasing for 2.5V logic, ADC references, and sensor interfaces
Max Output Current	300mA continuous - supports moderate-power peripherals like USB PHYs and small FPGAs
Dropout Voltage	400mV typ. at 300mA - enables operation down to 2.9V input for single-cell Li-ion or 3.3V rail post-regulation
Quiescent Current	50µA typ. at zero load - extends battery life in always-on monitoring circuits
PSRR	58dB at 100Hz - suppresses switching noise from upstream DC/DC converters
Thermal Resistance θ_JA	100°C/W (SOT89-3L, no heatsink) - defines safe power dissipation limit of 325mW at 85°C ambient
Protection Features	Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up and permanent damage under fault

Pinout & Package

SOT89-3L package: 3-pin surface-mount, thermally enhanced leadframe with exposed pad (not electrically connected), footprint per Diodes AP02007; suitable for high-reliability industrial PCBs with minimal thermal vias.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Regulated output	Delivers stable 2.5V; requires ≥10µF ceramic capacitor to ground for loop stability
2 (GND)	Power ground reference	Low-impedance return path; must be routed directly to power plane to minimize noise coupling
3 (IN)	Unregulated input	Accepts 2.7–5.5V; requires local 1µF bypass capacitor within 5mm of pin

Key Features

Feature	Design Value
PMOS pass element	1.5Ω R_ON enables zero gate-drive current, reducing system-level standby power
Fast transient response	Stabilizes within 10µs after 100mA load step - maintains voltage integrity during burst-mode MCU operation
Green RoHS-compliant molding	No Br/Sb halogens - meets IPC-1752A Tier 1 environmental reporting requirements
Short-circuit fold-back	Limits fault current to ≤300mA - avoids board-level fuse blowing and trace damage
Lead-free finish	Matte tin plating compatible with Pb-free reflow profiles (J-STD-020D)

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-output LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700-2502E/TO (Microchip)	250mA max output, 175mV dropout at 250mA, 2.5µA IQ - lower power but reduced current capability	Targeted at ultra-low-power sub-100mA sensors; insufficient for 300mA USB PHY loads	Select when IQ <5µA is mandatory and load never exceeds 250mA
TPS73225DBVR (TI)	250mA, 150mV dropout at 250mA, 400µA IQ, higher PSRR (65dB) - better noise rejection but higher quiescent draw	Better suited for RF/analog signal chains where PSRR >60dB is critical and battery life is secondary	Select when PSRR >60dB required and 400µA IQ acceptable in system budget

Compared with MCP1700-2502E/TO and TPS73225DBVR, AP130-25YG-13 uniquely balances 300mA drive, 400mV dropout, and 50µA IQ in a cost-effective SOT89-3L package - making it optimal for mid-power portable and industrial peripherals where thermal headroom and standby efficiency are co-constrained.

FAQ

What is the minimum input voltage required for AP130-25YG-13 to maintain regulation at 300mA?

The AP130-25YG-13 requires VIN ≥ VOUT + VDROP = 2.5V + 0.4V = 2.9V to sustain 300mA output while maintaining ±2% regulation. Below 2.9V, dropout occurs and output voltage drops linearly with input. The absolute minimum input rating is 2.7V, but regulation is not guaranteed below 2.9V at full load.

Can AP130-25YG-13 operate without an output capacitor?

No. A minimum 10µF ceramic capacitor is mandatory between OUT and GND to ensure loop stability and prevent oscillation. Omitting it causes sustained ringing or instability under load transients, as confirmed in the functional description section of DS31027 Rev. 8-2. Tantalum or aluminum electrolytic caps are not recommended due to ESR sensitivity.

Is the SOT89-3L package of AP130-25YG-13 thermally enhanced?

Yes. The SOT89-3L package features an exposed metal tab (pin 2 is GND, but the tab is internally connected to GND and serves as primary thermal path). Diodes specifies θ_JA = 100°C/W with no heatsink and no airflow - confirming its thermal enhancement over standard SOT23. PCB copper area under the tab significantly improves heat dissipation.

Does AP130-25YG-13 support reverse polarity or reverse current protection?

No. AP130-25YG-13 lacks internal reverse-voltage or reverse-current blocking. If input is disconnected while output remains biased (e.g., by another supply), current can flow backward from OUT to IN through the body diode of the PMOS pass device, potentially damaging upstream circuitry. An external series Schottky diode is required for reverse protection.
