Overview
The MC78PC33NTRG is a low noise, 150 mA Low Drop Out (LDO) linear voltage regulator from onsemi. This component is part of the MC78PC00 series, which features high output voltage accuracy, low supply current, low dropout voltage, and high ripple rejection. The MC78PC33NTRG is housed in a compact SOT-23 5-lead package, making it ideal for space-constrained applications. It is particularly suited for use in handheld communication equipment and other battery-powered devices due to its fast dynamic response to line and load changes.
