APPLICATION INFORMATION
programming the TPS75x01 adjustable LDO regulator
The output voltage of the TPS75x01 adjustable regulator is programmed using an external resistor divider as shown
in Figure 24. The output voltage is calculated using:
VO
Vref
1
R1
R2
(1)
Where:
V
ref
= 1.1834 V typ (the internal reference voltage)
Resistors R1 and R2 should be chosen for approximately 40-
μ
A divider current. Lower value resistors can be used
but offer no inherent advantage and waste more power. Higher values should be avoided as leakage currents at
FB
increase
the
output
voltage
error.
The
R2 = 30.1 k

NOTE: To reduce noise and prevent
oscillation, R1 and R2 need to be as close
as possible to the FB/SENSE terminal.
