LC1465CB5ATR33

LC1465 500mA High PSRR, Linear Regulator FEATURES DESCRIPTION LC1465 series are a group of positive voltage output, low power consumption, low dropout voltage regulators. It can provide foldback short-circuit protection and output current limit function. LC1465 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized on command. LC1465 can also work under a wide input voltage ranging from 2V to 7V. LC1465 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. LC1465 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within ±2%.  Input voltage range: 2 – 7V  Output voltage range: 1.0V~4.5V (customized on command every 0.1V step)  Low power consumption: 35uA (Typ.)  Low output noise (47uVRMS)  Shutdown mode: 0.1uA  Low dropout voltage: 300mV@300mA (Vout=3.3V) 500mV@500mA (Vout=3.3V)  High ripple rejection:70dB@1KHz (Typ.)  Low temperature coefficient: ±100ppm/C  Excellent line regulation: 0.05%/V  Build-in chip enable circuit  Highly accurate: ±2%  Output current limit 800mA@Vout=3.3V  Fold-back short circuit current 250mA@Vout=3.3V APPLICATIONS LC1465 is available in TSOT-23, SOT-23-3, SOT-235 and SOT89-3 packages which are lead free.      TYPICAL APPLICATION Power source for cellular phones and various kind of PCSs Battery Powered equipment Power Management of MP3, PDA, DSC, Mouse, PS2 Games Voltage Reference Regulation after Switching Power ELECTRICAL CHARACTERISTICS Vout Vin Vin 1uF LC1465 CE Vss Vout 1uF CE NOTE: Input capacitor (Cin=1uF) and Output capacitor (Cout=1uF) are recommended in all application circuit. www.leadchip.com 1 Your final power solution LC1465 ORDERING INFORMATION LC1465 □ 1 □ 2 □ 3 □ 4 Code PIN CONFIGURATION Product Classification F: Product Code X: Output Voltage Description Temperature&Rohs: C:-40~85C ,Pb Free Rohs Std.
