Dissipation and Thermal Design Section).
TYPICAL APPLICATION
GENERAL DESCRIPTION
The TCL1117 is a low-dropout positive voltage regula-
tor (LDO) with 800mA output current capability. It is available
in fixed and adjustable output voltage versions, 2.85V (ac-
tive SCSI terminators), 3.30V and 5.00V. Output/reference
voltage accuracy is guaranteed to ±1.0%. Over-current
protection is integrated onto the chip. Dropout is specified
at 1.2V maximum at full rated output current and less than
1.0V at low loads (<100mA). The SOT-223 package makes
the TCL1117 especially attractive for tight physical layouts.
For stability, a 10µF output capacitor is required. The
TCL1117 is an NPN-based design which has significantly
lower unused quiescent current than similar PNP-based
regulators.

NOTES: 1. Specifications apply over the full operating temperature range.
2. See thermal regulation specification for changes in output voltage due to heating effects. Load regulation and line regulation are
measured at a constant junction temperature by low duty cycle pulse testing.
3. Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/output
differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.
4. Minimum load current is defined as the minimum output current required to maintain regulation.
