2 Applications

  • RF Components VCOs, Receivers, ADCs, Amplifiers and Clock Distributions
  • Clean Analog Supply Requirements
  • Available in Military (–55°C to 125°C) Temperature Range
  • Engineering Evaluation (/EM) Samples are Available (1)
(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.
