A6300
LOW DROPOUT VOLTAGE REGULATOR 300mA CMOS WITH ENABLE PIN
DESCRIPTION
FEATURES
The A6300 is a series of CMOS positive linear regulators features enable pin function with low dropout voltage, making them ideal for battery powered applications.
The A6300 features a fixed output voltage for 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, 3.0V, 3.3V and 4.0V. The A6300 has both thermal shutdown and current limiting to prevent device failure under extreme operating conditions.
The A6300 features a typical 0.8Ω P-Channel MOSFET pass transistor. It provides several advantages over similar designs using PNP pass transistors, including longer battery life.
The A6300 is available in SOT-23, SOT-25, TSOT-25 and SC70-5 package.
Fixed Output Voltage: 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, 3.0V, 3.3V and 4.0V (Customized 0.1V Step Output Voltage)
Low Dropout Voltage: 0.18V@ 300mA (VOUT=3.3V)
High PSRR: 70dB @ 100Hz Quiescent Current: 67uA ( Typ.) Accurate within ±2% Excellent Line and Load Regulation Fast Response Output Current Limit and Thermal Shutdown Short Circuit Protection Low Temperature Coefficient Shutdown Current: 0.5uA Available in SOT-23, SOT-25, TSOT-25 and
SC70-5 package
