DESCRIPTION

Ultra low quiescent current (18µA typical)

Ultra low shutdown current (300nA typical)

< +/-2% V_OUTripple at no load

The LMR22007 is a switching regulator designed for

the high-efficiency requirement of applications with

stand-by and shut-down modes. The device features

a low-current mode to maintain efficiency under light-

load conditions, and an adaptive on-time control

architecture for fast transient response.

< +/-1% V_OUTripple at full load

Internal compensation, Soft-start and Thermal

Shutdown

Solution size less than 26mm²

The LMR22007 can deliver up to 750mA of

continuous load current with an adjustable input

current limit. The device has a wide input voltage

range of 2.7V to 20V, and supports V_INtransients to

24V. Other features include internal compensation,

internal soft start, input under-voltage protection,

internal bootstrap diode, and thermal shutdown.
