MAX8863
Pin-Compatible,
Low-Dropout, 120 mA
Linear Regulator
Delivering up to 120 mA, the MAX8863 is a fixed output,
low–dropout linear regulator that operates from a +2.5 V to +6.0 V
input range. The 50 µA supply current remains independent of load,
making these devices ideal for battery–operated portable equipment.
The output of the MAX8863 is preset at 3.15 V, 2.84 V, 2.80 V
or 1.80 V. (Other output voltage options are available – contact
ON Semiconductor for more information.) The MAX8863 is
pin–compatible with the Maxim MAX8863 LDO and is available in
the SOT–23–5 package.

*Stresses above those listed under “Absolute Maximum Ratings’’ may cause permanent damage to the device. These are stress ratings only
and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications
is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

1. Tested to EIA/JESD22–A114–A
2. Tested to EIA/JESD78
3. Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through correlation using
Statistical Quality Control (SQC) Methods.
4. Guaranteed by line regulation test.
5. Not tested. For design purposes, the current limit should be considered 150 mA minimum to 410 mA maximum.
6. The dropout voltage is defined as (VIN – VOUT) when VOUT is 100 mV below the value of VOUT for VIN = VOUT + 2.0 V.
