Microchip Technology recently launched a low dropout regulator (LDO), stable with ceramic capacitors, that operates at a very low supply current. Attachable to practically any microcontroller, this device is a low-cost, low-power LDO targeted at virtually any portable or battery-powered application.
Microchip's MCP1700 LDO can deliver up to 250mA of current while consuming only 1.6µA of quiescent current (typ). This device maximizes battery life with a dropout voltage of 178mV at 250mA; increases performance with an output voltage accuracy of 60.4% and exceeds in dynamic behavior with better line (6 .75%V) and load (61.0%V) regulation.
The MCP1700 enables the use of low-cost ceramic capacitors on the input and output, which reduces the system cost. Stable with a 1µF output capacitor, the overcurrent limit and overtemperature shutdown at this LDO provides a robust solution for any application.
Available in three-pin, SOT 23, SOT 89 and TO 92 packages. MCP1700, $0.39 (10,000).
