CM2865(A)E5
350mA CMOS LDO
HIGH ACCURACY VOUT 1.0%
GENERAL DESCRIPTION
FEATURES
The CM2865/A family is a positive voltage linear regulator
developed utilizing CMOS technology featured low quiescent
current (30μA typ.), low dropout voltage, and high output
voltage accuracy. Built-in low on-resistance transistor provides
low dropout voltage and large output current. A 1.0μF or
greater can be used as an output capacitor.
The SOT-89 and SOT-223 packages are attractive for
“Pocket” and “Hand Held” applications.
These robust devices are designed to prevent device failure
under the worst operation condition with both Thermal
Shutdown and Current Fold-back.

DETAILED DESCRIPTION
CM2865(A)E5
350mA CMOS LDO
HIGH ACCURACY VOUT 1.0%
The CM2865 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current
protection and thermal shutdown.
The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal protection circuits.
During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal
shutdown circuits become active when the junction temperature exceeds 175℃, or the current exceeds 350mA. During thermal
shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120℃.
EXTERNAL CAPACITOR
The CM2865 is stable with an output capacitor to ground of 1.0μF or greater. It can keep stable even with higher or poor ESR
capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be
larger than 0.1μF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground
termination is desirable.
