BL8567 300mA, Wide Input Voltage, Low Consumption Linear Regulator GENERAL DESCRIPTION FEATURES BL8567 series are a group of positive voltage output, high precise, and high PSRR and low power consumption voltage regulator. Voltages are selectable in 100mV steps within a range of 2.5V to 5V. It also can be customized on command. • • • • • • • BL8567 series have 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%. Low Quiescent Current: 8uA at 5V High PSRR: 60dB range to 10KHz Low Output Noise: 44uVRMS Low Dropout: 270mV at 150mA load Low Temperature Coefficient: ±100ppm/°C Excellent Line Regulation: 0.05%/V Highly Accurate: ±2% APPLICATIONS • • • • • BL8567 series are available in SOT-23-3, SOT-23-5,SOT-89-3 packages, which are lead (Pb)- free. Reference Voltage Source Battery Powered Equipment Hand-Hold Equipment Wireless LAN GPS Receivers TYPICAL APPLICATION Note 1: Input capacitor (CIN=1uF) is recommended in all applications. Note 2: Output capacitor (COUT=1uF/6.8uF) is recommended in all applications to assure the stability of circuit. 1uF Tantalum capacitor or 6.8uF ceramic capacitor is recommended.
