150mA LDO Regulator with PowerOK O/P
To get maximum battery life from portable equipment, Low Drop Out (LDO) regulators are often used. These devices can supply a well regulated output voltage while having a drop-out voltage (Vin – Vout) of only 100 mV. Battery powered equipment always has a problem when the battery voltage falls and the regulator can no longer maintain its designed output voltage. Operation of the circuit becomes unreliable and data can be lost.
