Description
The AP7370 series is a positive voltage regulator IC.
(Top View)
NEW PRODUCT
The AP7370 has features of wide input voltage range, high accuracy,
low dropout voltage, current limit, reverse current protection, and
ultra-low quiescent current which make it ideal for use in various USB
and portable devices and instrument application.
The IC consists of a voltage reference, an error amplifier, a resistor
network for setting output voltage, a current limit circuit for current
protection, and a chip enable circuit.

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and
Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain 2.5V
IOUT ≤ 150mA
VDROP
Min
µA
4. Measured with VIN = VOUT + 3V for VOUT ≤ 2.5V. Measured with VIN = VOUT + 2.5V for VOUT > 2.5V.
5. VDROP is measured with VIN = 0.98 VOUT(Nom).
6. Dropout is only valid when VOUT ≥ 2.8V because of the minimum input voltage limits.
