Description
MCP1792/3 100 mA High-Voltage Automotive LDO Features AEC-Q100 with Grade 0 and PPAP Capable Wide Input Voltage Range: 4.5V to 55V - Up to 70V transient - Under Voltage Lock Out (UVLO): 2.7V typical Extended Operating Temperature Range: -40°C to +150°C Standard Output Regulated Voltages (VR): 3.3V and 5.0V (Note) - Tolerance  2.0% typical Low Quiescent Supply Current: 25 µA typical Low Shutdown Quiescent Supply Current: 2 µA typical Output Current Capability: 100 mA typical - Short Circuit Current Foldback Protection - Thermal Shutdown Protection: 175°C Stable with Ceramic Output Capacitor: 2.2 µF High PSRR: - 80 dB @ 100 Hz typical - 55 dB @ 100 kHz typical Available in the following packages: - 3-Lead SOT-223 (MCP1792) - 3-Lead SOT-23A (MCP1792) - 5-Lead SOT-223 (MCP1793) - 5-Lead SOT-23 (MCP1793) Applications Automotive Electronics Microcontroller Biasing High-Voltage Battery Packs for Power Tools, ebikes, etc Smoke Detectors and other Alarm Sensors Typical Application Description The MCP1792/3 family devices are high-voltage, low dropout (LDO) regulators, capable of generating 100 mA output current. The input voltage range of 4.5V to 55V makes it suitable in 12V to 48V power rails and in high-voltage battery packs. A low UVLO at shutdown of 2.4V makes it adequate for cold cranking conditions in automotive applications. The MCP1792/3 comes in two standard fixed output voltage versions: 3.3V and 5.0V. The regulator output is stable with 2.2 µF...
