Product details
Overview
AP7361E-FGE-7 from Diodes Incorporated is a 1A ultra-low dropout linear regulator with adjustable/fixed output voltage, enable control, and power-good monitoring. It delivers ±1% output accuracy, 360mV dropout at 3.3V/1A, 60µA quiescent current, and operates from 2.2V–6.0V input for battery-powered audio/video systems and portable electronics.
For engineers reviewing the AP7361E-FGE-7 datasheet, AP7361E-FGE-7 pinout, AP7361E-FGE-7 application, or AP7361E-FGE-7 equivalent, key selection criteria include dropout performance at full load, PG threshold hysteresis (±3%), thermal shutdown at +150°C, and compatibility with 2.2µF MLCC output capacitors without external compensation.
Technical Context
The AP7361E integrates a PMOS pass element, band-gap reference, error amplifier, and fold-back current limiting. Its PG output uses an open-drain MOSFET with 89–95% rising threshold and 79–85% falling threshold relative to VOUT, enabling precise supply sequencing.
Thermal shutdown activates at +150°C with +20°C hysteresis, and the device remains stable across -40°C to +85°C ambient using ceramic, tantalum, or solid polymer output capacitors ≥2.2µF - no minimum load required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.0A maximum continuous - supports single-rail power for SoC core or I/O domains in portable devices. |
| Dropout Voltage | 360mV typical at 3.3V/1A - enables regulation from 3.66V input, critical for Li-ion battery discharge tail-end operation. |
| Quiescent Current | 60µA typical - minimizes standby power loss in always-on subsystems like real-time clocks or sensor hubs. |
| Output Accuracy | ±1% over line/load/temperature - ensures reliable logic-level compliance for 1.8V/2.5V/3.3V digital interfaces. |
| PSRR | 75dB @ 1kHz - suppresses switching noise from upstream DC-DC converters feeding sensitive analog circuitry. |
| PG Threshold Hysteresis | ±3% (92% rise / 82% fall) - prevents false toggling during marginal output voltage conditions during load transients. |
| Thermal Shutdown | +150°C activation with +20°C hysteresis - provides robust protection under sustained overload or poor PCB thermal design. |
Pinout & Package
AP7361E-FGE-7 is housed in the U-DFN3030-8 (Type E) package - a 3.0mm × 3.0mm, 0.6mm height, thermally enhanced leadless package with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Regulated output | Connects to load; requires ≥2.2µF ceramic capacitor to GND for stability and transient response. |
| 2, 6 NC | No connection | Unbonded pins - must remain floating; no routing or soldering required. |
| 3 ADJ/NC | Feedback reference node | Used only in adjustable version to set VOUT via resistor divider; tied to OUT in fixed-output variants. |
| 4 GND | Power ground | Main return path for IN, OUT, EN, and PG; must connect directly to low-impedance ground plane. |
| 5 EN | Enable control input | Active-high logic interface (VIH ≥ 1.0V); internal 3.0MΩ pull-down ensures default-off state if left unconnected. |
| 7 PG | Power-good status indicator | Open-drain output requiring external 10kΩ–1MΩ pull-up; sinks ≤0.4V at 5mA when VOUT falls below 82% of nominal. |
| 8 IN | Input supply | Accepts 2.2V–6.0V; requires ≥1µF ceramic bypass capacitor placed adjacent to pin for noise rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 360mV at 3.3V/1A enables >90% efficiency at end-of-battery discharge in 3.7V Li-ion systems. |
| Integrated power-good | Open-drain PG with 3% hysteresis enables reliable sequencing of downstream regulators or microcontroller reset assertion. |
| Fold-back short-circuit protection | Limits fault current to 400mA during output short, reducing thermal stress and enabling safe auto-recovery. |
| Stability with low-ESR capacitors | Operates stably with ≥2.2µF MLCC, eliminating need for bulk electrolytic or series resistance tuning. |
| Low-temperature coefficient | ±100ppm/°C output drift ensures <±1.7% total variation across -40°C to +85°C ambient range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826T-3302E/OT | Fixed 3.3V output; 1.2A rating; 450mV dropout at 1A; no PG output; 85µA IQ | Lacks power-good signaling and adjustable option; higher dropout reduces usable input range | Select when PG and adjustability are unnecessary and higher output current margin is required |
| TLS850F0TES/V33 | Automotive-grade AEC-Q100 qualified; 500mA rating; 200mV dropout at 3.3V; integrated watchdog timer | Lower current capacity; automotive qualification adds cost and lead time; includes safety features not needed in consumer gear | Select only for automotive infotainment modules requiring functional safety compliance |
Compared with MCP1826T-3302E/OT and TLS850F0TES/V33, AP7361E-FGE-7 uniquely balances 1A capability, 360mV dropout, ±1% accuracy, PG monitoring, and 60µA IQ in a compact DFN package - making it optimal for space-constrained, battery-sensitive consumer electronics where sequencing and low-noise regulation are essential.

FAQ
What is the minimum output capacitor value required for stability?
The AP7361E-FGE-7 is stable with any ≥2.2µF ceramic, tantalum, or solid polymer capacitor - no ESR requirement or external compensation needed. MLCCs are preferred for lowest ESL and best high-frequency transient response. Larger values improve load step recovery but do not affect loop stability.
Can the EN pin be left unconnected?
No - the EN pin has an internal 3.0MΩ pull-down resistor, but leaving it floating risks noise-induced toggling. For always-on operation, tie EN directly to IN. For controlled enable, drive with a clean logic signal meeting VIH ≥ 1.0V and VIL ≤ 0.3V specifications.
How does the PG pin behave during thermal shutdown?
During thermal shutdown, the PG pin is actively pulled low by the internal MOSFET - identical to its behavior when EN is low or VOUT drops below 82% of nominal. This provides unambiguous fault indication regardless of failure mode (overload, overtemp, or undervoltage).
Is the AP7361E-FGE-7 RoHS and halogen-free compliant?
Yes - AP7361E-FGE-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen-free per Diodes' "Green" definition: <900ppm Br, <900ppm Cl (total Br+Cl <1500ppm), and <1000ppm Sb compounds - verified per JESD22-A112 testing.
