APPLICATIONS INFORMATION Note to Reader: To avoid confusion when working with negative voltages (is –6V more or less than –5V?), I have decided to treat the LT1175 were a positive regulator and express all voltages as positive ...

LT1175 APPLICATIONS INFORMATION normally a good thing when the regulator is used by itself, but it prevents the user from shutting down the regulator when a second power source is connected to the LT1175 output. If active output pull-down is ...

APPLICATIONS INFORMATION LT1175 AC FEEDFORWARD PATH NEGATIVE DC FEEDBACK Q3 AT LIGHT LOADS This condition can occur with ceramic or fi lm capacitors which often have an ESR under 0.1Ω. With previous de- signs, the user was forced to add ...

LT1175 APPLICATIONS INFORMATION capacitors do not fail during a “shorting out” surge, only during a “charge up” surge. The output capacitor should be located within several inches of the regulator. If remote sensing is used, the output capacitor can be ...

... Input Voltage Lower Than Output Linear Technology’s positive low dropout regulators LT1121 and LT1129, will not draw large currents if the input voltage is less than the output. These devices use a lateral PNP power transistor structure that has 40V emitter base breakdown voltage ...

LT1175 APPLICATIONS INFORMATION To estimate regulator output ripple under different conditions, the following general comments should be helpful: 1. Output ripple at high frequency is only weakly affected by load current or output capacitor size for medium to heavy loads. ...
