NCP706A 1 A, 1% Precision Very Low Dropout Voltage Regulator with Enable and Active Discharge The NCP706A is a Very Low Dropout Regulator which provides up to 1 A of load current and maintains excellent output voltage accuracy of 1% including line, load and temperature variations. The operating input voltage range from 2.4 V up to 5.5 V makes this device suitable for Li−ion battery powered products as well as post−regulation applications. The product is available in 3.0 V fixed output voltage option. NCP706A is fully protected against overheating and output short circuit. Very small 8−pin XDFN8 1.6 x 1.2, 04P package makes the device especially suitable for space constrained portable applications such as tablets and smartphones. Parts feature active output discharge function. Features • Operating Input Voltage Range: 2.4 V to 5.5 V • Fixed Output Voltage Option: 3.0 V Other Output Voltage Options Available on Request. • Low Quiescent Current of Typ. 200 mA • Very Low Dropout: 155 mV Max. at IOUT = 1 A • ±1% Accuracy Over Load/Line/Temperature • High PSRR: 60 dB at 1 kHz • Internal Soft−Start to Limit the Inrush Current • Thermal Shutdown and Current Limit Protections • Stable with a 1.0 mF Ceramic Output Capacitor • Available in XDFN8 1.6 x 1.2, 04P 8−pin Package • Active Output Discharge • These are Pb−Free Devices Typical Applications • Tablets, Smartphones, • Wireless Handsets, Portable Media Players • Portable Medical Equipment • Other Battery Powered Applications VIN = 2.4 (3.3) − 5.5 V IN OUT CIN NCP706A EN SNS ON OFF GND VOUT = 3.0 V @ 1 A COUT 1.0 mF Ceramic www.onsemi.com XDFN8 CASE 711AS MARKING DIAGRAM AEMG G AE = Specific Device Code M = Date Code G = Pb−Free Package (Note: Microdot may be in either location) PIN CONNECTION OUT 1 8 IN OUT 2 7 IN N/C 3 6 EN SNS 4 5 GND (Top View) IN 8 1 OUT IN 7 2 OUT EN 6 3 N/C GND 5 4 SNS (Bottom View) ORDERING INFORMATION See detailed ordering, marking and shipping information on page 8 of this data sheet.

Simplified Internal Schematic Block Diagram PIN FUNCTION DESCRIPTION Pin No. XDFN8 Pin Name Description 1 OUT Regulated output voltage. A minimum 1.0 mF 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. 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 NCP706A ABSOLUTE MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage (Note 1) VIN −0.3 V to 6 V V Output Voltage VOUT −0.3 V to VIN + 0.3 V V Enable Input VEN −0.3 V to VIN + 0.3 V V Output Short Circuit Duration tSC Indefinite s Maximum Junction Temperature TJ(MAX) 150 °C Storage Temperature TSTG −55 to 150 °C ESD Capability, Human Body Model (Note 2) ESDHBM 2000 V ESD Capability, Machine Model (Note 2) ESDMM 200 V Stresses exceeding those listed in the Maximum Ratings table may damage the device.
