EL7535 pdf datasheet (Monolith

The EL7535 is a synchronous, integrated FET 350mA
step-down regulator in a 10 Ld MSOP package. The regulator
is internally compensated, which makes it possible to use just
five tiny external components to form a complete DC/DC
converter. The regulator operates with an input voltage range
from 2.5V to 6V, which accommodates supplies of 3.3V, 5V, or
a Li-Ion battery source. The output can be externally set from
0.8V to VIN with a resistive divider.
The EL7535 features PWM mode control. The operating
frequency is typically 1.4MHz. Additional features include
<1μA shut-down current, short-circuit protection, and
over-temperature protection.
The EL7535 is available in the 10 Ld MSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.
