3 Description
The TPS7H1x01 is a LDO linear regulator that uses a
PMOS pass element configuration. It operates under
a wide range of input voltage, from 1.5 to 7 V while
offering excellent PSRR. The TPS7H1x01 features a
precise and programmable fold back current limit
implementation with a very-wide adjustment range.
To support the complex power requirements of
FPGAs, DSPs, or microcontrollers, the TPS7H1x01
provides enable on/off functionality, programmable
SoftStart, current sharing capability, and a
PowerGood open-drain output. The TPS7H1x01 is
available in a thermally-enhanced 16-pin ceramic
flatpack package (CFP) and KGD (bare die) package.

(1) Custom temperature ranges are available
(2) These units are intended for engineering evaluation only.
They are processed to a noncompliant flow (that is, no burn-
in, and so forth) and are tested to a temperature rating of
25°C only. These units are not suitable for qualification,
production, radiation testing or flight use. Parts are not
warranted for performance over the full MIL specified
temperature range of –55°C to 125°C or operating life.
