3 Description
The TPS7H1101-SP is a radiation-hardened 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 TPS7H1101-SP features a precise and
programmable foldback current limit implementation
with a very-wide adjustment range. To support the
complex power requirements of FPGAs, DSPs, or
microcontrollers, the TPS7H1101-SP provides enable
on and off functionality, programmable SoftStart,
current sharing capability, and a PowerGood open-
drain output.

(1) 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.
(2) For all available packages, see the orderable addendum at
the end of the data sheet.
