(A) Output capacitor selection is critical for regulator stability. Larger COUT values benefit the regulator by improving transient response and loop stability. This device is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR between 0.2 Ω and 10 Ω.
(B) CADJ can be used to improve ripple rejection. If CADJ is used, a COUT that is larger in value than CADJ must be used.
(C) CIN is recommended if the TLV1117
is not located near the power-supply filter.
(D) An external diode is recommended to protect the regulator if the input instantaneously is shorted to GND.
