NCP4683

NCP4683 300 mA, Low Dropout Regulator The NCP4683 is a CMOS Linear voltage regulator with 300 mA output current capability. The device has high output voltage accuracy, low supply current and high ripple rejection. The NCP4683 is easy to use, with output current fold−back protection circuit included. A Chip Enable function is included to save power by lowering supply current. The line and load transient responses are very good, thus this regulator is suitable for use as a power supply for communication equipment. Features Operating Input Voltage Range: 1.40 V to 5.25 V Output Voltage Range: 0.8 V to 3.6 V (available in 0.1 V steps) Output Voltage Accuracy: ±1.0% (VOUT > 2.0 V) Supply Current: 50 mA Dropout Voltage: 0.25 V (IOUT = 300 mA, VOUT = 2.8 V) High PSRR: 70 dB (f = 1 kHz) Line Regulation: 0.02%/V Typ. Stable with Ceramic Capacitors: 1.0 mF or more Current Fold Back Protection Available in UDFN4 1.0 x 1.0 mm, SC−70, SOT23 Packages These are Pb−Free Devices Typical Applications Battery−powered Equipment Networking and Communication Equipment Cameras, DVRs, STB and Camcorders Home Appliances VIN C1 1m NCP4683x VIN VOUT CE GND VOUT C2 1m www.onsemi.com MARKING DIAGRAMS SOT−23−5 CASE 1212 XXX M SC−70 CASE 419A XXX XMM 1 UDFN4 CASE 517BR XX MM 1 XX, XXX, XXXX = Specific Device Code M, MM = Date Code ORDERING INFORMATION See detailed ordering, marking and shipping information in the package dimensions section on page 18 of this d...
