Datasheet MCP1804 (Microchip)

MCP1804 150 mA, 28V LDO Regulator With Shutdown Features: Description:
• 150 mA Output Current The MCP1804 is a family of CMOS low dropout (LDO) • Low Dropout Voltage, 260 mV Typical @ 20 mA, voltage regulators that can deliver up to 150 mA of V current while consuming only 50 µA of quiescent R = 3.3V • 50 µA Typical Quiescent Current current (typical, 1.8V  VOUT  5.0V). The input operating range is specified from 2.0V to 28.0V. • 0.01 µA Typical Shutdown Current • Input Operating Voltage Range: 2.0V to 28.0V The MCP1804 is capable of delivering 100 mA with only 1300 mV (typical) of input to output voltage • Standard Output Voltage Options differential (V (1.8V, 2.5V, 3.0V, 3.3V, 5.0V, 10.0V, 12.0V) OUT = 3.3V). The output voltage tolerance of the MCP1804 at +25°C is a maximum of ±2%. Line • Output Voltage Accuracy: ±2% regulation is ±0.15% typical at +25°C. • Output Voltages from 1.8V to 18.0V in 0.1V The LDO input and output are stable with 0.1 µF of Increments are Available upon Request input and output capacitance. Ceramic, tantalum or • Stable with Ceramic Output Capacitors aluminum electrolytic capacitors can all be used for • Current Limit Protection with Current Foldback input and output. Overcurrent limit with current foldback • Shutdown Pin to 40 mA (typical) provides short circuit protection. • High PSRR: 50 dB Typical @ 1 kHz A shutdown (SHDN) function allows the output to be enabled or disabled. When disabled, the MCP1804
