5 / 9 page SI-3010KM 1 A, Low-Dropout, 1.0~16 V Regulator www.allegromicro.com Linear Regulators 5 APPLICATIONS INFORMATION Input Capacitor (C I, ≥22 µF). This is necessary either when the input line includes inductance or when the wiring is long. Output Capacitor (C O, ≥47 µF). This device is not designed for a use with a very low ESR output capacitor such as a ceramic capacitor. Output oscillation may occur with that kind of capacitor. The recommended ESR is 0.2~2 Ω at T A = 25°C. Reverse-Bias Protection Diode (D1). Diode D1 provides reverse-bias protection between the input and output. Sanken type SFPL-52 is recommended. ENABLE Input. The ENABLE (control) input features an internal pull-down resistor. Leaving this input open causes the output to turn off. Parallel Operation. Parallel operation to increase load current is not permitted. TYPICAL CHARACTERISTICS (cont.) (VI = 7 V, VO = 5.0 V adjusted, TA = 25°C) Overvoltage Protection GND Pin Current Output Voltage Adjustable Resistors (R1 and R2). The output voltage is adjusted by R1 and R2. 10 k Ω for R2 is recommended. R1 = (V O – Vref)/(Vref/R2) For an output voltage of 1.5 V or less, diode D1 can be eliminated and add a 10 k Ω resistor between ADJ and the junction of R1 and R2. |
