ST662ABD-TRY

Voltage Regulators - DC DC Switching Regulators Overview

The ST662ABD-TRY is an automotive-grade regulated charge pump DC-DC converter manufactured by STMicroelectronics. It provides a fixed 12 V ± 5% output voltage to program byte-wide Flash memory and can supply up to 30 mA of output current from an input voltage as low as 4.75 V. The device features a logic-controlled shutdown pin that interfaces directly with microprocessors, reducing supply current to only 1 uA. It is available in an SO-8 package and is qualified according to the AEC-Q100 specification for the automotive market, operating within a temperature range of -40°C to +125°C.
