PT7M8218 includes a reference voltage source, an error amplifier, a driver transistor, a current limit protection, a thermal protection and an internal phase compensator. The output voltage for the regulator is set by factory trimming within a range of 0.9V to 3.3V in 100mV step includes 2.85V. PT7M8218 is stable with low ESR ceramic capacitors. PT7M8218 is available in SC70-5L and SOT23-5L packages. It operates over a temperature range of -40 to +85°C. Pin Assignment SC70-5L /SOT23-5L Pin Description Pin No I/O Pin Name Description 1 I VIN Regulator Supply Input. Supply voltage can range from 1.7V to 5.5V. Bypass with a 0.47F ceramic capacitor (X5R/X7R) to GND. 2 P GND Ground. 3 I EN ON/OFF Control of Regulator. High active. 4 - NC This pin is better to be connected to the GND, but leaving it open is also acceptable 5 O VOUT Output of Regulator. Bypass with a 0.47F ceramic capacitor (X5R/X7R) to GND. NC VOUT GND EN 2 3 4 1 5 VIN |
