Description
300mA Low Dropout
Regulator in 3-pin package Very low IQ over full load: 65µA Wide input voltage range: 2V to 6V Fixed output options: 1.0V to 3.3V PSRR: 65dB typical at 100Hz Fast start-up time: 80µs Stable with low ESR, 1µF ceramic output capacitor Excellent Load/Line Transient Response Low dropout: 300mV typical at 300mA Current limit protection Short circuit protection Thermal shutdown protection Ambient temperature range: -40ºC to 85°C SOT23 and SOT23R: Available in “Green” Molding
Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note 1)
The AP7333 is a 300mA, fixed output voltage, low dropout linear
regulator. The device included pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry.
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 AP7333 is available in SOT23 packages with different pin-outs.
