Product details

Overview

AP130-20YRG-13 from Diodes Incorporated is a fixed 2.0V, 300mA low-dropout linear regulator in SOT89R-3L package with 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy-designed for battery-powered peripherals requiring stable low-voltage rail generation.

For engineers reviewing the AP130-20YRG-13 datasheet, AP130-20YRG-13 pinout, AP130-20YRG-13 application, or AP130-20YRG-13 equivalent, key selection criteria include dropout performance under 300mA load, thermal resistance (θ_JA = 100°C/W), short-circuit fold-back protection, and RoHS-compliant green packaging compatibility with high-density PCB layouts.

Technical Context

The AP130-20YRG-13 integrates a PMOS pass element with no base current draw, an internal 1.08V bandgap reference, error amplifier, and thermal shutdown circuitry. Its architecture enables fast transient response and stable operation with only 10µF output capacitance.

It operates across 2.7V–5.5V input range while maintaining regulation down to 2.4V input at 2.0V output (400mV dropout), with built-in current limit (450mA typ) and short-circuit fold-back limiting peak fault current to 300mA.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.0V ±2% - ensures precise biasing for 2.0V logic or analog subsystems without external feedback.
Max Output Current	300mA continuous - supports moderate-power peripherals like USB interface ICs or sensor signal chains.
Dropout Voltage	400mV at 300mA - enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min) sources.
Quiescent Current	50µA typical - minimizes standby power loss in always-on battery applications such as remote sensors.
PSRR	58dB at 100Hz - suppresses low-frequency ripple from switching DC/DC stages upstream of LDO input.
Thermal Resistance θ_JA	100°C/W (SOT89R-3L) - allows 1.2W max power dissipation at 85°C ambient before thermal shutdown triggers.
Protection Features	Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or permanent damage during overload or miswiring.

Pinout & Package

SOT89R-3L package: 3-pin surface-mount, exposed thermal pad (not electrically connected), 4.5mm × 2.5mm footprint, 1.5mm height, RoHS-compliant green molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1: GND	Ground reference	Primary return path for load current and internal bias; connects to PCB ground plane for thermal and noise control.
2: IN	Input voltage supply	Accepts 2.7–5.5V unregulated input; requires ≥1µF ceramic bypass capacitor close to pin.
3: OUT	Regulated output	Delivers stable 2.0V; requires ≥10µF low-ESR output capacitor for loop stability and transient response.

Key Features

Feature	Design Value
PMOS pass transistor	Zero gate drive current eliminates base-current dependency-reduces input supply burden vs. NPN-based LDOs.
Fast transient response	Stabilizes within <10µs after 100mA step load change-critical for burst-mode digital loads like RF transceivers.
Load regulation	±40mV over 1–300mA load range-maintains tight voltage window for ADC references or PLL VCO supplies.
Green packaging	No Br/Sb halogen content per JEDEC J-STD-609-meets environmental compliance for global industrial shipments.
Short-circuit fold-back	Limits output current to ≤150mA when V_OUT < 1.05V-reduces power dissipation and junction temperature during sustained fault.

Applications

Wireless Sensor Node

USB Peripheral Controller

Use Scenario: Sub-1W IoT node powered by CR2032 or single Li-ion cell with intermittent BLE transmission.

IC Role / Device Role / Timing Role: Primary 2.0V supply for microcontroller core and RF transceiver IC.

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
AP2202K-2.0TRG1	200mA rated, SOT23-5 package, higher quiescent current (80µA), no fold-back protection	Lower current capacity limits use to ultra-low-power logic; lacks short-circuit robustness for motor-driven peripherals	Select when board space is constrained and thermal load is minimal; verify load does not exceed 200mA.
MCP1700T-2002E/TT	250mA rated, SOT23-3, 1.6µA quiescent current, but 600mV dropout at 250mA	Better battery life in standby, but cannot regulate below 2.6V input-unsuitable for deep-discharge Li-ion operation	Prefer for energy-harvesting or coin-cell applications where ultra-low IQ dominates over dropout; avoid for 2.4–2.7V input windows.

Compared with AP2202K-2.0TRG1 and MCP1700T-2002E/TT, the AP130-20YRG-13 uniquely balances 300mA capability, 400mV dropout, and fold-back protection in a thermally efficient SOT89R-3L package-making it optimal for cost-sensitive, medium-current embedded systems where reliability under fault conditions is mandatory.

FAQ

What is the minimum input voltage required for AP130-20YRG-13 to maintain 2.0V output at 300mA?

The AP130-20YRG-13 requires a minimum input voltage of 2.4V to sustain 2.0V output at 300mA load, based on its 400mV typical dropout voltage specification. Operation below this threshold results in unregulated output and potential system reset due to brownout.

Can AP130-20YRG-13 be used with ceramic output capacitors?

Yes-the AP130-20YRG-13 is stable with ceramic output capacitors ≥10µF and ESR ≤100mΩ. The datasheet explicitly recommends low-ESR ceramics for optimal transient response and avoids the need for tantalum or aluminum electrolytic alternatives.

Does AP130-20YRG-13 require an input bypass capacitor?

Yes-a minimum 1µF ceramic capacitor must be placed between IN and GND, located within 2mm of the device pins. This reduces high-frequency input impedance and prevents oscillation caused by PCB trace inductance interacting with the internal control loop.

How does the short-circuit fold-back protection behave during sustained fault conditions?

Under short-circuit, the AP130-20YRG-13 reduces output current to 150–300mA (typical) once V_OUT drops below 1.05V. This fold-back action lowers power dissipation and junction temperature, allowing indefinite safe operation without thermal shutdown-unlike hard current-limit designs that would overheat.
