MCP1781 High-Voltage LDO Regulators

Microchip Technology MCP1781 High-Voltage Low Dropout (LDO) Regulators are capable of generating 200mA of output current. The input voltage range of 4.3V to 55V makes it suitable for 12V to 48V power rails and high-voltage battery packs, as well as automotive applications that operate through large transients, such as load dump. A low UVLO at shutdown of 2.3V makes it adequate for cold cranking conditions in automotive applications. The MCP1781 comes in two standard fixed-output-voltage versions (3.3V and 5.0V) and an adjustable-output option with a voltage range from 1.3V to 5V. The regulator output is stable with 3.3µF ceramic capacitors. The device is protected against short-circuit events by the current foldback function and against overheating by thermal shutdown protection. The Microchip Technology MCP1781 is available in two 5-lead packages, SOT-223 and TO-252, both of which have a PGOOD and a SHDN pin. During shutdown, the quiescent current drops to 3.5µA, reducing overall power consumption. The device itself has a typical ground current of 45µA while delivering a maximum output current of 200mA.
