NCP706B, NCP706AB Voltage Regulator - 1% Precision Very Low Dropout, Enable 1 A The NCP706B/AB are a Very Low Dropout Regulators family www.onsemi.com which provides up to 1 A of load current and maintains excellent output voltage accuracy of 1% including line, load and temperature MARKING variations. The operating input voltage range from 2.4 V up to 5.5 V DIAGRAM makes this device suitable for Liion battery powered products as well as postregulation applications. The product is available in 3.0 V fixed XXM XDFN8 output voltage option. NCP706B/AB are fully protected against CASE 711AS overheating and output short circuit and includes latched OCP protection which automatically latchesoff the device in the case of a XX = Specific Device Code short circuit event and the NCP706AB has internal active discharge M = Date Code circuit. = PbFree Package Very small 8pin XDFN8 1.6 x 1.2, 04P package makes the device (Note: Microdot may be in either location) especially suitable for space constrained portable applications such as tablets and smartphones.

Simplified Internal Schematic Block Diagram PIN FUNCTION DESCRIPTION Pin No. XDFN8 Pin Name Description 1 OUT Regulated output voltage. A minimum 2.2 F ceramic capacitor is needed from this pin to ground to assure stability. 2 OUT 3 N/C Not connected. This pin can be tied to ground to improve thermal dissipation. 4 SNS Remote sense connection. This pin should be connected to the output voltage rail. 5 GND Power supply ground. 6 EN Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode. In case of the NCP706B/AB pulling the EN low resets the OCP latch state. 7 IN Input pin. A small capacitor is needed from this pin to ground to assure stability. 8 IN Exposed This pad enhances thermal performance and is electrically connected to GND. It is recommended Pad that the exposed pad is connected to the ground plane on the board or otherwise left open. www.onsemi.com 2
