NCP1117, NCV1117 APPLICATIONS INFORMATION Introduction Frequency compensation for the regulator is provided by The NCP1117 features a significant reduction in dropout capacitor C and its use is mandatory to ensure output out voltage along with enhanced output voltage accuracy and stability. A minimum capacitance value of 4.7 (cid:2)F with an temperature stability when compared to older industry equivalent series resistance (ESR) that is within the limits of standard three−terminal adjustable regulators. These 33 m(cid:3) (typ) to 2.2 (cid:3) is required. See Figures 12 and 13. The devices contain output current limiting, safe operating area capacitor type can be ceramic, tantalum, or aluminum compensation and thermal shutdown protection making electrolytic as long as it meets the minimum capacitance them designer friendly for powering numerous consumer value and ESR limits over the circuit’s entire operating and industrial products. The NCP1117 series is pin temperature range. Higher values of output capacitance can compatible with the older LM317 and its derivative device be used to enhance loop stability and transient response with types. the additional benefit of reducing output noise.

Cin + 1 Vref R1 +Cout develop and maintain the nominal 1.25 V reference voltage Iadj + between the output and adjust pins. The reference voltage is R2 Cadj programmed to a constant current source by resistor R1, and this current flows through R2 to ground to set the output (cid:6) (cid:8) voltage. The programmed current level is usually selected to Vout(cid:2)Vref 1(cid:7)R2 (cid:7)IadjR2 be greater than the specified 5.0 mA minimum that is R1 required for regulation. Since the adjust pin current, Iadj, is Figure 24. Adjustable Output Regulator significantly lower and constant with respect to the programmed load current, it generates a small output The output ripple will increase linearly for fixed and voltage error that can usually be ignored. For the fixed adjustable devices as the ratio of output voltage to the output devices R1 and R2 are included within the device and reference voltage increases. For example, with a 12 V the ground current Ignd, ranges from 3.0 mA to 5.0 mA regulator, the output ripple will increase by 12 V/1.25 V or depending upon the output voltage. 9.6 and the ripple rejection will decrease by 20 log of this ratio or 19.6 dB. The loss of ripple rejection can be restored External Capacitors to the values shown with the addition of bypass capacitor Input bypass capacitor C may be required for regulator in Cadj, shown in Figure 24. The reactance of Cadj at the ripple stability if the device is located more than a few inches from frequency must be less than the resistance of R1. The value the power source. This capacitor will reduce the circuit’s of R1 can be selected to provide the minimum required load sensitivity when powered from a complex source impedance current to maintain regulation and is usually in the range of and significantly enhance the output transient response.
