LT1934/LT1934-1

Micropower Step-Down

Switching Regulators

in ThinSOT and DFN

FEATURES

DESCRIPTION

TheLT^®1934isamicropowerstep-downDC/DCconverter

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 shut-

down mode disconnects the load from the input source,

simplifying power management in battery-powered sys-

tems. Burst Mode^®operation and the low drop internal

power switch result in high efﬁciency over a broad range

of load current.

Wide Input Voltage Range: 3.2V to 34V

Micropower Operation: I = 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 V

Switch: 200mV at 300mA

CESAT

Low Proﬁle (1mm) SOT-23 (ThinSOT™) and

(2mm × 3mm × 0.8mm) 6-Pin DFN Package

APPLICATIONS

The LT1934 provides up to 300mA of output current. The

LT1934-1 has a lower current limit, allowing optimum

choice of external components when the required output

current is less than 60mA. Fast current limiting protects

the LT1934 and external components against shorted

outputs, even at 34V input.
