APL5155

APL5155 High Input Voltage, Low Quiescent Current, 150mA LDO Regulator Features Wide Input Voltage Range: 5.4V to 25V Ultra Low Ground Current: 10 µA High Output Accuracy: ±2.5% Excellent Load/Line Transient Low Dropout Voltage: 750mV @ 150mA Fixed Output Voltages for 5V/3.3V or Adjustable Voltage Built-In Current-Limit Protection Built-In Over-Temperature Protection Zero Shutdown Current Internal Soft-Start Function POR Scheme to Prevent VOUT Spike SOT-23-5, SOT-89, and SOP-8P Packages Lead Free and Green Devices Available (RoHS Compliant) General Description The APL5155 is a low ground current linear regulator, which operates with input voltage from 5.4V to 25V and delivers output current up to 150mA. Typical dropout voltage is only 750mV at 150mA loading. This combination of the high voltage and the low ground current makes the APL5155 ideal for USB and portable devices, using 2cell or 3-cell Li-Ion battery inputs. The APL5155 is stable with aluminum, tantalum, and ceramic capacitors. It requires a 1 µF or greater capacitor for stability. The APL5155 has many protection functions, including over-temperature, current-limit and short circuit current limit protections, which prevent the device from thermal over-load and current over-load. The APL5155 regulator is available in miniature SO T-235, SOT-89, and SOP-8P packages.
