SI-3010KM Allegro Microsystems Inc, SI-3010KM Datasheet - Page 5

• Manufacturer Part Number: SI-3010KM
• Description: Regulator IC - Low Dropout Voltage (Surface Mount)
• Manufacturer: Allegro Microsystems Inc

Input Capacitor (C
when the input line includes inductance or when the wiring
is long.
Output Capacitor (C
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
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.

Output Voltage Adjustable Resistors (R1 and R2).
The output voltage is adjusted by R1 and R2. 10 k
R2 is recommended.
For an output voltage of 1.5 V or less, diode D1 can be
eliminated and add a 10 k resistor between ADJ and the
junction of R1 and R2.
