MIC5333 Datasheet, PDF (9/12 Pages) Micrel Semiconductor – Micro-Power High Performance Dual 300mA ULDO™ with Dual POR

Micrel, Inc.
0.42W = (125°C – T_A)/(75°C/W)
T_A = 93.5°C
Therefore, a 3.0V/2.8V application with 300mA at each
output current can accept an ambient operating
temperature of 93.5°C in a 2.5mm x 2.5mm MLF^®
package. For a full discussion of heat sinking and
MIC5333
thermal effects on voltage regulators, refer to the
“Regulator Thermals” section of Micrel’s Designing with
Low-Dropout Voltage Regulators handbook. This
