• Available in Military (–55°C to 125°C)
Temperature Range
• Engineering Evaluation (/EM) Samples are
Available
(1) _{These units are intended for engineering evaluation only.}
They are processed to a non-compliant flow (for example, 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
specified for performance over the full MIL specified
temperature range of –55°C to 125°C or operating life.
3 Description
The TPS7A4501-SP is a low-dropout (LDO) regulator
optimized for fast-transient response. The 5962-
1222402VHA can supply 750 mA of output current
with a dropout voltage of 300 mV. The
5962R1222403VXC can supply 1.5 A of output
current with a dropout voltage of 320 mV. Quiescent
current is well controlled; it does not rise in dropout,
as with many other regulators. In addition to fast
transient response, the TPS7A4501-SP regulator has
very-low output noise, which makes it ideal for
sensitive RF supply applications.
