1 Introduction

The TPS7H1111-SP is an ultra-low noise, high PSRR, low dropout linear regulator (LDO) optimized for powering RF (radio frequency) devices in a space environment. It is capable of sourcing up to 1.5 A over a 0.85-V to 7-V input range with a 2.2-V to 14-V bias supply.

The EVM is configured with a default output resistor to regulate to a 1.8 V VOUT, with a usable VIN range of
(1.8 V + VDO) to 7 V with VBIAS range of (VOUT + 1.6 V to 14 V). Worst case VDO ranges from 430mV for VBIAS ≥ (VOUT + 1.6 V) to 1.4 V with VBIAS = VIN across recommended operating conditions. The EVM is intended to aid engineers in the evaluation of the operation and performance of the TPS7H1111-SP linear regulator. The TPS7H1111-SP low-dropout regulator allows input voltages from 0.85 V to 7 V and is capable of regulating any output voltage between 0.4 V and up to 5.5 V by changing the VOUT current setting resistor R8. The EVM is capable of delivering up to 1.5 A to a load. Achieving the maximum load depends on multiple variables, including the input-output power dissipation, board thermal dissipation, and heat removal.
