5 Pin Configuration and Functions
Figure 5-1 DBV Package,5-Pin SOT-23(Top View)Table 5-1 Pin Functions
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| ADJ | 4 | I/O | Feedback pin to set the output voltage with help of the feedback divider. See the Recommended Operating Conditions section for more information. |
| GND | 2 | — | Ground |
| ON/OFF | 3 | 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. |
| VIN | 1 | I | Input supply pin. Use a capacitor with a value of 1 μF or larger from this pin to ground. See the Input and Output Capacitor Requirements section for more information. |
| VOUT | 5 | O | Output of the regulator. Use a capacitor with a value of 4.7 μF (for legacy chip) and 2.2 μF (for new chip) or larger from this pin to ground.(1) See the Input and Output Capacitor Requirements section for more information. |
(1) The nominal output capacitance
must be greater than 1 μF (for the new chip) and 2.2 μF (for the legacy chip).
Throughout this document, the nominal derating on these capacitors is 50%. Make
sure that the effective capacitance at the pin is greater than 1 μF (for the new
chip) and 2.2 μF (for the legacy chip).
