Package
The LP2985IM5-5.0 is a low-dropout (LDO) linear voltage regulator from Texas Instruments. It is packaged in a SOT-23-5 package, which is a small-outline, surface-mount package with five leads.
Pinout
The LP2985IM5-5.0 is a low-dropout (LDO) voltage regulator. It comes in a 5-pin SOT-23 package. Here’s a brief description of its pin functions:
1. Vout (Pin 1): This is the output pin where the regulated 5.0V is provided.
2. GND (Pin 2): This is the ground pin, which is connected to the circuit ground.
3. SHDN (Pin 3): This is the shutdown pin. It is used to enable or disable the regulator. When connected to a high logic level, the regulator is in shutdown mode, reducing the quiescent current.
4. Bypass (Pin 4): This pin is used to connect an external capacitor for noise reduction and improving the power supply rejection ratio (PSRR).
5. Vin (Pin 5): This is the input pin for the unregulated voltage supply.
The LP2985IM5-5.0 is suitable for applications that require a stable 5V output with low input-output voltage differential.
