Figure 7-2. LP2992 Typical Application
7.2.1 Design Requirements
Minimum COUT value for stability (can be increased without limit for improved stability and transient response)
ON/OFF must be actively terminated. Connect to VIN if shutdown feature is not used.
Optional BYPASS capacitor for low-noise operation.
7.2.2 Detailed Design Procedure
7.2.2.1 ON/OFF Operation
The LP2992 allows for a shutdown mode using the ON/OFF pin. Driving the pin LOW (≤ 0.4V) turns the device
OFF; conversely, a HIGH (≥ 1.2V) turns the device ON. If the shutdown feature is not used, connect ON/OFF to
the input so that the regulator is on at all times. For proper operation, do not leave ON/OFF unconnected.
