LC1465 500mA High PSRR, Linear Regulator FEATURES DESCRIPTION Input voltage range: 2 7V LC1465 series are a group of positive voltage Output voltage range: 1.0V~4.5V (customized output, low power consumption, low dropout on command every 0.1V step) voltage regulators. It can provide foldback Low power consumption: 35uA (Typ.) short-circuit protection and output current limit Low output noise (47uVRMS) function. Shutdown mode: 0.1uA Low dropout voltage: LC1465 can provide output value in the range of 300mV 300mA (Vout=3.3V) 1.0V~4.5V every 0.1V step. It also can be 500mV 500mA (Vout=3.3V) customized on command. LC1465 can also work High ripple rejection:70dB 1KHz (Typ.) under a wide input voltage ranging from 2V to 7V. Low temperature coefficient: 100ppm/C Excellent line regulation: 0.05%/V LC1465 includes high accuracy voltage reference, Build-in chip enable circuit error amplifier, current limit circuit and output Highly accurate: 2% driver module. Output current limit 800mA Vout=3.3V LC1465 has excellent load and line transient Fold-back short circuit current response and good temperature characteristics, 250mA Vout=3.3V which can assure the stability of chip and power system. And it uses trimming technique to APPLICATIONS guarantee output voltage accuracy within 2%. Power source for cellular phones and various LC1465 is available in TSOT-23, SOT-23-3, SOT-23- kind of PCSs 5 and SOT89-3 packages which are lead free. Battery Powered equipment Power Management of MP3, PDA, DSC, Mouse, PS2 Games Voltage Reference Regulation after Switching Power TYPICAL APPLICATION ELECTRICAL CHARACTERISTICS Vin Vout Vin Vout LC1465 CE 1uF 1uF Vss 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 PIN CONFIGURATION LC1465 1 2 3 4 Product Classification LC1465CB3ATR Code Description F: Product Code Temperature&Rohs: X: Output Voltage 1 C:-40~85 C ,Pb Free Rohs Std.
