FEATURES
s s s s s s s s s DESCRIPTIO Wide Input Voltage Range: 3.2V to 34V Micropower Operation: IQ = 12µA 5V at 250mA from 6.5V to 34V Input (LT1934) 5V at 60mA from 6.5V to 34V Input (LT1934-1) 3.3V at 250mA from 4.5V to 34V Input (LT1934) 3.3V at 60mA from 4.5V to 34V Input (LT1934-1) Low Shutdown Current: <1µA Low VCESAT Switch: 200mV at 300mA Low Profile (1mm) SOT-23 (ThinSOTTM) Package U APPLICATIO S s s s s s The LT ®1934 is a micropower step-down DC/DC converter with internal 400mA power switch, packaged in a low profile (1mm) ThinSOT. With its wide input range of 3.2V to 34V, the LT1934 can regulate a wide variety of power sources, from 4-cell alkaline batteries and 5V logic rails to unregulated wall transformers and lead-acid batteries. Quiescent current is just 12µA and a zero current shutdown mode disconnects the load from the input source, simplifying power management in battery-powered systems. Burst Mode® operation and the low drop internal power switch result in high efficiency over a broad range of load current.
