• Manufacturer Part Number: MAX8532EBTG
• Description: Low-Noise, Low-Dropout, 200mA Linear Regulator in UCSP
• Manufacturer: MAXIM [Maxim Integrated Products]

The MAX8532 load-transient response graphs (see the
Typical Operating Characteristics) show two compo-
nents of the output response: a DC shift in the output
voltage due to the different load currents, and the tran-
sient response. Increase the output capacitor’s value
and decrease its ESR to attenuate transient spikes.
A regulator’s minimum input/output voltage differential
(or dropout voltage) determines the lowest usable supply
voltage. In battery-powered systems, this determines
the useful end-of-life battery voltage. Because the
MAX8532 uses a P-channel MOSFET pass transistor, its
dropout voltage is a function of drain-to-source on-
resistance (R
the Typical Operating Characteristics).
The maximum output power of the MAX8532 can be lim-
ited by the maximum power dissipation of the package.

Ascertain the maximum power dissipation by calculat-
ing the power dissipation of the package as a function
of the input voltage, output voltage, and output current.
The maximum power dissipation should not exceed the
