SP6200/6201 100/200mA CMOS LDO Regulator
Copyright 2004 Sipex Corporation
Note 1.
Exceeding the absolute maximum rating may damage the device.
Note 2.
The device is not guaranteed to function outside its operating rating.
Note 3.
The maximum allowable power dissipation at any T
(ambient temperature) is P
= (T
– T
) /
θ
A
.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will
go into thermal shutdown. The
θ
of the SP6200/6201 (all versions) is 90
°
C/W for the SOT-23-5 and 59
°
C/W for
the DFN package on a standard 4 layer board (see “Thermal Considerations” section for further details).
Note 4.
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note 5.
Load Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are
tested for load regulation in the load range; from 0.1mA to 100mA, SP6200; from 0.1mA to 200mA, SP6201. Changes
in output voltage due to heating effects are covered by the thermal regulation specification. Not applicable to output
voltages less than 2.5V.
Note 6.
Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below
its nominal value measured at 1V differential. Not applicable to output voltages less than 2.7V.
Note 7.
Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum
of the load current plus the ground pin current.
Note 8.
Thermal regulation is defined as the change in output voltage at a time ”t” after a change in power dissipation
is applied, excluding load or line regulation effects. Specifications are for a 100mA load pulse at V
IN
= 6V for t = 10ms.
