PRODUCTION DATA
This user’s guide describes operational use of the TPS7H1111EVM evaluation module (EVM) as a reference design for engineering demonstration and evaluation of the TPS7H1111-SEP and TPS7H1111-SP (QMLP), 1.5-A, Ultra-Low Noise, High PSRR, Space Enhanced Plastic, Lowdrop Out (LDO) regulators. This user's guide provides details about the EVM, its configuration, schematics, and bill of material (BOM).

The TPS7H1111-SEP 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 at 1.5 A load. The EVM is intended to aid engineers in the evaluation of
the operation and performance of the TPS7H1111-SEP linear regulator. The TPS7H1111-SEP
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.
