MAX5092 Description
The MAX5092A/MAX5092B/MAX5093A/MAX5093B lowquiescent-current, low-dropout (LDO) regulators contain simple boost preregulators operating at a high frequency. The devices seamlessly provide a preset 3.3V (MAX5092A/MAX5093A) or 5V (MAX5092B/MAX5093B) LDO output voltage from an automotive cold-crank through load-dump (3.5V to 80V) input voltage conditions. The MAX5092_/MAX5093_ deliver up to 250mA with excellent load...
