DESCRIPTION

The

ST755

is

an

adjustable

inverting

switch-mode

DC-DC rergulator with

internal

Power MOSFET that generaters an adjustable

negative output from a voltage input of 2.7V to

11V, output

current guaranteed at 200mA (for

SO-8

Vin>4.5V, Vout = -5V and 0

oC

≤ Ta ≤ 70oC) and

275mA (typical value at Ta =25

oC, Vout = -5V).

A logic controlled shut down pin that interfaces

directly with microprocessor reduces supply

current to only 10

µA. Input to Output differential

voltage is limited to Vin+|Vout|<12.7V. No load

supply current is 1.2mA.
