This user's guide describes the characteristics, operation, and use of the TPS780xxEVM-301 evaluation
module (EVM). This EVM demonstrates the Texas Instruments TPS780330220 ultra low-power, low
dropout (LDO) regulator with pin-selectable, dual-output voltage levels. The TPS780330220 supplies up to
150 mA of output current at a pin programmable output voltage of 3.3 V (V
from a 2.2 V to 5.5 V input source. See the TPS780330220 data sheet (SBVS083) for definitive device
specifications. This EVM user's guide includes setup instructions, schematic diagram, bill of materials
(BOM), and PCB layout drawings.

Introduction
The TPS780xxEVM-301 evaluation module (EVM) assists designers in evaluating the operation and
performance of the TPS780330220 low dropout regulator (LDO). This LDO provides up to 150 mA of
output current at a pin-programmable output while maintaining ultra-low quiescent current (I
The board features the small 2 mm × 2 mm six-lead SON package (DRV) and the TSOT23-5 (DDC)
package for small solution size.
