MCP1793T-3302H/OT Microchip

MCP1792/3 100 mA High-Voltage Automotive LDO Features Description AEC-Q100 with Grade 0 and PPAP Capable The MCP1792/3 family devices are high-voltage, low dropout (LDO) regulators, capable of generating Wide Input Voltage Range: 4.5V to 55V 100 mA output current. The input voltage range of 4.5V - Up to 70V transient to 55V makes it suitable in 12V to 48V power rails and - Under Voltage Lock Out (UVLO): 2.7V typical in high-voltage battery packs. Extended Operating Temperature Range: -40C A low UVLO at shutdown of 2.4V makes it adequate for to +150C cold cranking conditions in automotive applications. Standard Output Regulated Voltages (V ): 3.3V R The MCP1792/3 comes in two standard fixed output and 5.0V (Note) voltage versions: 3.3V and 5.0V. The regulator output - Tolerance 2.0% typical is stable with 2.2 F ceramic capacitors. The device is Low Quiescent Supply Current: 25 A typical protected from short-circuit events by the current Low Shutdown Quiescent Supply Current: foldback function and from overheating by means of 2 A typical thermal shutdown protection. Output Current Capability: 100 mA typical The MCP1792 is the 3-lead version of the MCP1792/3 - Short Circuit Current Foldback Protection device family and the MCP1793 is the 5-lead version, - Thermal Shutdown Protection: 175C which offers shutdown functionality (SHDN pin). While in shutdown, the quiescent current drops to 2A, Stable with Ceramic Output Capacitor: 2.2 F allowing for lower, overall power consumption. The High PSRR: device itself has a ground current of 100 A typical, - 80 dB 100 Hz typical while delivering maximum output current of 100 mA. - 55 dB 100 kHz typical Note: For other voltage options, contact your Available in the following packages: local sales office. - 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 9 9 9 9 QWURO&ROH U 9 9 7 28 ,1 & ,1 & 287 ) ) 99 9 *1 P V PV P V V W P V P V V P Overvoltage Line Transient 2019-2022 Microchip Technology Inc. and its subsidiaries DS20006229D-page 1 *1 *1 6+ 1 9 0&3 % 7 9 9 9MCP1792/3 Package Types 3-Pin SOT-23A 5-Pin SOT-23 3-Pin SOT-223 5-Pin SOT-223 TOP VIEW V IN GNDGND GND 44 3 6 V 1 5 V IN OUT GND 2 3 SHDN 4 NC 1 2 11 22 33 12 3 45 GND V OUT VV ININ GNDGND VV OUOUTT SHDN V GNDV NC IN OUT 2019-2022 Microchip Technology Inc. and its subsidiaries DS20006229D-page 2
