Pinout
The LP2985AIM5-3.3 is a low-dropout (LDO) linear voltage regulator with a fixed output voltage of 3.3 volts. It typically comes in a 5-pin SOT-23 package. Here is a concise summary of its pin functions:
1. VIN (Pin 1): Input voltage supply pin. Connect the input voltage source to this pin.
2. GND (Pin 2): Ground pin. This serves as the return path for input and output currents.
3. SHUTDOWN (Pin 3): Shutdown pin. When pulled low, it disables the regulator, reducing its quiescent current. Pulling it high or leaving it unconnected enables the regulator.
4. BYPASS (Pin 4): Bypass pin. Connecting a capacitor between this pin and ground can improve the noise performance by lowering output noise.
5. VOUT (Pin 5): Output voltage pin. It provides the regulated output voltage of 3.3V.
The LP2985AIM5-3.3 is ideal for applications requiring efficient regulation with low dropout voltage and low noise performance. It is commonly used in portable devices and battery-powered applications.
