    Figure 28. Typical Application Circuit (Fixed Versions)
    programming the TPS76501 adjustable LDO regulator
    The output voltage of the TPS76501 adjustable regulator is programmed using an external resistor divider as
    shown in Figure 29. The output voltage is calculated using:
    VO
    Vref
    1
    R1
    R2
    (1)
    Where
    V
    ref
    = 1.224 V typ (the internal reference voltage)
    Resistors R1 and R2 should be chosen for approximately 7-
    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 recommended design procedure is to choose
    R2 = 169 k
    to set the divider current at 7
    μ
    A and then calculate R1 using:
    R1
    VO
