... Output Capacitor The RT9183 is designed specifically to work with very small ceramic output capacitors. The recommended minimum capacitance (temperature characteristics X7R or X5R) are 10μF to 47μF range with 10mΩ to 25mΩ range ceramic capacitors between each LDO output and GND for transient stability, but it may be increased without limit ...

... ESR is maximum. Thermal Considerations Thermal protection limits power dissipation in RT9183. When the operation junction temperature exceeds 170°C, the OTP circuit starts the thermal shutdown function and turns the pass element off. The pass element turns on again after the junction temperature cools by 30° ...

... RT9183 Adjustable Operation The adjustable version of the RT9183 has an output voltage range of 0.8V to 4.5V. The output voltage is set by the ratio of two external resistors as shown in Figure 2. The value of R2 should be less than 80k to maintain regulation. In critical applications, small voltage drop is caused by the resistance (R ...
