ZHCSU10P March 2000 – February 2025 LP2981-N
PRODUCTION DATA
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | IN | I | Input supply pin. Use a capacitor with a value of 1μF or larger from this pin to ground. See the Input and Output Capacitor Requirements section for more information. |
| 2 | GND | — | Common ground (device substrate). |
| 3 | ON/OFF | I | Enable pin for the LDO. Driving the ON/OFF pin high enables the device. Driving this pin low disables the device. High and low thresholds are listed in the Electrical Characteristics table. Tie this pin to VIN if unused. |
| 4 | NC | — |
DO NOT CONNECT. Device pin 4 is reserved for post packaging test and calibration of the LP2981-N VOUT accuracy. Device pin 4 must be left floating. Do not connect to any potential. Do not connect to ground. Any attempt to do pin continuity testing on device pin 4 is discouraged. Continuity test results are variable depending on the actions of the factory calibration. Aggressive pin continuity testing (high voltage, or high current) on device pin 4 can activate the trim circuitry forcing VOUT to move out of tolerance. |
| 5 | OUT(1) | O | Output of the regulator. Use a capacitor with a value of 2.2μF or larger from this pin to ground. See the Input and Output Capacitor Requirements section for more information. |
