TPS715xx Family of LDO Regulators
1-2
Introduction
1.1 TPS715xx Family of LDO Regulators
The TPS715xx family of LDO regulators is comprised of small SOT–223/PICO
packaged regulators capable of delivering 50 mA of output current. Features
of the part include:
- 50-mA Low-Dropout Regulator
- 24-V Maximum Input Voltage
- Low 4.25-µA Quiescent Current at 50 mA
- 5-Pin PICO/SC70 (DCK) Package
- Stable With Any Ceramic Capacitor (>0.47 µF)
- Dropout Voltage Typically 100 mV at 50 mA
- Over Current Limitation
- –40°C to 125°C Operating Junction Temperature Range
1.2 EVM Design Strategy
The purpose of this EVM is to facilitate evaluation of the TPS715xx family of
LDO regulators. Each EVM PCB contains a TPS71533 low dropout linear
regulator as well as supporting passive components. Also, the board’s small
size and side clips facilitate attaching it to other PCBs as a power module.
1.3 Schematic
Figure 1-1 shows the SLVP199 PCB schematic diagram, which is used as the
PCB for the TPS71533EVM.
