Overview
Features AP7311 150mA, Low Quiescent Current, Fast Transient Low Dropout Linear Regulator Description • 150mA Low Dropout Regulator with EN • Very low IQ over full load: 65µA • Wide input voltage range: 2V to 6V • Wide adjustable output: 0.
8V to 5.
0V • Fixed output options: 1.
0V to 3.
3V • PSRR: 65dB at 100Hz • Fast start-up time: 80µs • Stable with low ESR, 1µF ceramic output capacitor • Excellent Load/Line Transient Response • Low dropout: 150mV typical at 150mA • Current limit protection • Short circuit protection • Thermal shutdown protection • Ambient temperature range: -40ºC to 85°C • SOT25: Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/RoHS Compliant (Note 1) The AP7311 is a 150mA, adjustable and fixed output voltage, low dropout linear regulator.
The device included pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry.
The device is turned on when EN pin is set to logic high level.
The characteristics of low dropout voltage and low quiescent current make it suitable for low power applications, for example, battery powered devices.
The typical quiescent current is approximately 65μA.
Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions.
The AP7311 is available in SOT25 package.
