Product details

Overview

AP130-30RG-7 from Diodes Incorporated is a 300mA fixed-output 3.0V low-dropout linear regulator in SC59R package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and fold-back short-circuit protection-designed for battery-powered portable electronics requiring stable low-noise voltage regulation.

For engineers reviewing the AP130-30RG-7 datasheet, AP130-30RG-7 pinout, AP130-30RG-7 application, or AP130-30RG-7 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θ_JA = 250°C/W), SC59R pin compatibility, and green/RoHS-compliant packaging for space-constrained PCBs.

Technical Context

The AP130-30RG-7 employs a PMOS pass transistor with internal 1.5Ω R_ON, enabling ultra-low quiescent current independent of load. Its bandgap reference and error amplifier deliver tight line/load regulation (0.3%/V and 40mV respectively) across –40°C to +85°C ambient.

Protection circuitry includes thermal shutdown triggered at ~150°C junction temperature and current limit set at 350–450mA with fold-back behavior below 1.05V output-ensuring safe operation during sustained overload or short-circuit events without external components.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±2% at 1mA load; ensures stable core logic supply for 3.3V-tolerant microcontrollers.
Dropout Voltage	400mV typ. at 300mA; enables regulation from 3.4V input-critical for single-cell Li-ion or dual-cell alkaline systems.
Quiescent Current	50µA typ. at zero load; minimizes standby power loss in always-on IoT sensors and wearables.
PSRR	58dB at 100Hz; suppresses ripple from switching DC/DC stages upstream of sensitive analog or RF circuitry.
Thermal Resistance θ_JA	250°C/W (SC59R); requires minimal copper area for thermal management in compact handheld PCB layouts.
Current Limit	350–450mA with fold-back; limits fault power dissipation to <150mW during short-circuit-prevents board-level thermal runaway.
Operating Input Range	2.7V to 5.5V; supports wide-input applications including USB-powered peripherals and industrial 3.3V rails.

Pinout & Package

AP130-30RG-7 uses the SC59R package: 3-pin SOT-23 variant with reversed pinout (GND–OUT–IN, top view). This layout simplifies PCB routing in high-density designs where ground plane access is prioritized.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for error amplifier and thermal sensor; must connect to low-impedance PCB ground plane.
2	OUT	Regulated 3.0V output; requires ≥10µF ceramic capacitor to ground for stability per datasheet.
3	IN	Input supply (2.7–5.5V); needs local 1µF bypass capacitor near pin to suppress high-frequency noise.

Key Features

Feature	Design Value
PMOS Pass Element	No gate/base drive current required-eliminates bias network losses and improves light-load efficiency.
Fast Transient Response	Stabilizes within 10µs after 100mA load step; maintains <±30mV output deviation for real-time MCU clock domains.
Green Molding Compound	Halogen-free (no Br/Sb); meets IPC-4101D/21 and JEDEC J-STD-020 moisture sensitivity level 1.
Short-Circuit Fold-Back	Reduces output current to 150–300mA when V_OUT < 1.05V-limits junction temperature rise during sustained shorts.
Lead-Free & RoHS Compliant	SnAgCu (SAC305) termination; qualified to JEDEC J-STD-020C reflow profile with peak 260°C.

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
MCP1700T-3002E/TT (Microchip)	250mA rating, 175mV dropout at 250mA, 2.0µA quiescent current	Lower IQ suits ultra-low-power sleep modes but insufficient for 300mA peak loads	Select only if peak current ≤250mA and standby IQ <5µA is mandatory
TPS73030DBVR (TI)	300mA rating, 120mV dropout at 300mA, 330µA IQ, SOT-23-5 package	Lower dropout enables 3.12V minimum input; extra enable pin adds control flexibility	Choose when input headroom is <3.12V or system-level enable sequencing is required

Compared with MCP1700T-3002E/TT and TPS73030DBVR, AP130-30RG-7 delivers optimal balance of 300mA capability, 400mV dropout, and 50µA IQ in a 3-pin SC59R footprint-making it ideal for cost-sensitive, space-constrained designs where moderate dropout and robust protection are prioritized over ultra-low IQ or sub-200mV dropout.

FAQ

What is the minimum input voltage required for AP130-30RG-7 to maintain regulated 3.0V output at 300mA?

The minimum input voltage is 3.4V, calculated as V_OUT + V_DROP = 3.0V + 0.4V (typical dropout at 300mA). The device guarantees regulation down to this differential; operation below 3.4V results in unregulated output proportional to input.

Can AP130-30RG-7 be used without an output capacitor?

No. A minimum 10µF ceramic capacitor is mandatory between OUT and GND for stability, as confirmed in the Functional Descriptions section. Omitting it causes oscillation and potential damage due to phase margin loss in the internal feedback loop.

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

When output voltage drops below 1.05V, the current limit folds back to 150–300mA (per datasheet Table on p.4), reducing power dissipation to <150mW. This prevents thermal runaway and allows indefinite fault survival without shutdown-unlike latch-off protection schemes.

Is AP130-30RG-7 compatible with lead-free reflow soldering processes?

Yes. It uses SnAgCu (SAC305) terminations and is qualified to JEDEC J-STD-020C with peak reflow temperature of 260°C. The SC59R package withstands standard lead-free profiles without delamination or solder joint failure.
