The quiescent current is typically 150µA at light loads and only 165µA at 500mA. This is 5% more efficient than equivalent Bi-CMOS devices that can waste up to 25mA at 500mA. Load regulation is maintained for peak currents up to 500mA. This is useful for supplying inrush currents during power-up and transient conditions. Continuous output current is limited by package type and board layout. A dedicated control input (EN, Active High) has been included for power-up sequencing flexibility. When this input is taken low, the regulator is disabled. In this state, the supply current will drop to near zero. The device also features reverse current protection. This protects the device by blocking the pass transistors parasitic diode when the output voltage is forced higher than the input. For low noise performance and increased power supply ripple rejection a noise bypass capacitor can be connected to the BYP pin. Connecting this capacitor will not significantly delay the speed of power-up. The CM3019 is fully protected, offering both overload current limiting and high temperature thermal shutdown. To reduce board cost and layout size the CM3019 was designed to be stable with or without any output capacitor. This includes tiny, low ESR ceramic capacitors. Housed in a low profile MSOP8 package, or a SOT23- 5/SOT23-6, the device is ideal for space critical applications. Typical Application Circuit Block Diagram |
