EL7531
FN7428.9
Monolithic 1A Step-Down Regulator with
Low Quiescent Current
The EL7531 is a synchronous, integrated FET 1A step-down
regulator with internal compensation. It operates with an input
voltage range from 2.5V to 5.5V, which accommodates
supplies of 3.3V, 5V, or a Li-Ion battery source. The output can
be externally set from 0.8V to V IN with a resistive divider.
The EL7531 features automatic PFM/PWM mode control, or
PWM mode only. The PWM frequency is typically 1.4MHz
and can be synchronized up to 12MHz. The typical no load
quiescent current is only 120μA. Additional features include
a Power-Good output, <1μA shut-down current, short-circuit
protection, and over-temperature protection.
The EL7531 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.15 in 2 of
PCB area with components on one side only. The 10 Ld
MSOP package is specified for operation over the full -40°C
to +85°C temperature range.
