LDO Supports Wide Input Range

Microchip Technology’s MCP1702 Low Dropout Regulator (LDO) drives up to 250 mA with low quiescent current and high input voltage. The LDO is ideal for applications requiring long battery run-times and high tolerance for input-voltage variations, such as smoke detectors.

With a low quiescent current of 2 μA, the MCP1702 supports input voltages up to 13.2 V. The MCP1702 LDO also features device- and circuit-protection capabilities such as overcurrent protection and thermal shutdown, enabling users to more effectively avoid system failures. In addition to highly accurate output-voltage regulation, the LDO includes ±2% percent over-temperature accuracy.

Samples of the MCP1702 LDO are available now. The device is available in 3-pin SOT-89, SOT-23 and TO-92 packages. Pricing is $0.37 each in 10,000-unit quantities for all package types.
