Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the B-type designation affect the Chip Enable (CE) pin functionality?

The 'B' designation indicates the absence of a pull-down resistor but includes an internal auto-discharge switch. This allows the output capacitor charge to be discharged rapidly to the VSS level when the CE pin receives a low-level signal.

What is the mechanism for reverse current protection in this regulator?

The IC incorporates reverse current protection to prevent damage to connected products like batteries. When the input voltage is lower than the output voltage, the circuit suppresses reverse current flow from the VOUT pin to the VIN pin to a maximum of 1.5μA.
