Diodes Incorporated AP7361E-10FGE-7

Overview

AP7361E-10FGE-7 from Diodes Incorporated is a 1A fixed-output (1.0V) ultra-low dropout linear regulator with enable and power-good functions, designed for precision voltage regulation in space-constrained, low-power systems. It delivers ±1% output accuracy, 360mV dropout at 1A (for 3.3V version), 60µA quiescent current, and operates across 2.2V–6.0V input range.

For engineers reviewing the AP7361E-10FGE-7 datasheet, AP7361E-10FGE-7 pinout, AP7361E-10FGE-7 application, or AP7361E-10FGE-7 equivalent, key selection criteria include its U-DFN3030-8 (Type E) package thermal performance (θJA = 70°C/W), open-drain PG threshold (89–95% VOUT), EN logic thresholds (VIH ≥ 1.0V), and stability with ≥2.2µF MLCC output capacitors.

Technical Context

The AP7361E-10FGE-7 integrates a PMOS pass element, band-gap reference (0.8V), error amplifier, and fold-back current limiting (400mA short-circuit clamp). Its fixed 1.0V output eliminates external resistor divider requirements while retaining full enable and power-good monitoring capability.

Thermal shutdown activates at +150°C with +20°C hysteresis, and the PG pin provides sequencing control via open-drain output with 10kΩ–1MΩ pull-up compatibility up to 6V - independent of VIN. The device maintains regulation down to zero load and supports fast turn-on (<200µs ramp time) without sacrificing quiescent current efficiency.

FAQ

What is the minimum input voltage required for AP7361E-10FGE-7 to regulate 1.0V output?

The minimum input voltage is 2.2V per datasheet specifications. At 1.0V output, the dropout voltage is 710mV at 300mA, meaning VIN must be ≥1.71V to maintain regulation - but the absolute minimum VIN allowed is 2.2V due to internal circuitry requirements and absolute maximum ratings constraints.

Can AP7361E-10FGE-7 be used without an external pull-up on the PG pin?

No - the PG pin is open-drain and requires an external pull-up resistor (10kΩ to 1MΩ) to a voltage rail ≤6V to generate a valid logic-high signal. Without it, PG remains floating and cannot indicate power-good status reliably, compromising system sequencing and fault detection.

Does AP7361E-10FGE-7 require a minimum load current to maintain regulation stability?

No - the device is specified for stable operation from zero load to full 1.0A output. Its internal compensation and architecture eliminate the need for minimum load resistors, simplifying design for intermittent-duty applications like sensor wake-up circuits or standby logic rails.

Is the U-DFN3030-8 (Type E) package of AP7361E-10FGE-7 lead-free and RoHS compliant?

Yes - AP7361E-10FGE-7 is fully RoHS compliant (2015/863/EU), totally lead-free, halogen-free, and antimony-free per Diodes Incorporated's "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb), with manufacturing certified to IATF 16949 standards.
