Capacitor Selection and Regulator Stability
Ceramic capacitors are highly recommended as they offer distinct advantages over their tantalum and aluminum elec-
trolytic components.
For stable operation with load currents up to 150mA over the entire device temperature range, use a 1μF (min)
ceramic output capacitor with an ESR <0.2 Ω .
Use large output capacitor values (10μF max) to reduce noise and improve load transient-response, stability and
power-supply rejection.
Note: Some ceramic capacitors exhibit large capacitance and ESR variations with variations in temperature. Z5U
and Y5V capacitors may be required to ensure stability at temperatures below T AMB = -10oC. With X7R or X5R
capacitors, a 1μF capacitor should be sufficient at all operating temperatures.
Power Supply Rejection Ratio
The AS1353/AS1356 are designed to deliver low dropout voltages and low quiescent currents. Power-supply rejection
is 60dB (typ) at low frequencies. To improve power supply-noise rejection and transient response, increase the values
of the input and output bypass capacitors (see Figure 13).
The Typical Operating Characteristics (page 6) show the device line- and load-transient responses. See the Power-
Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics section (page 6) for further
details.
Dropout Voltage
For standard products with output voltage greater than the minimum V IN (2.5V), the minimum input-output voltage dif-
ferential (dropout voltage) determines the lowest usable supply voltage. This determines the useful end-of-life battery
voltage in battery-powered systems.
The dropout voltage is a function of the P-MOSFET drain-to-source on-resistance multiplied by the load current, and is
calculated by:
V DROPOUT = V IN - V OUT = R DS(ON) x I OUT
Where:
R DS(ON) is the drain-to-source on-resistance.
I OUT is the supply current.
See Typical Operating Characteristics (page 6) for further information.
