Data Sheet
To guarantee the performance of the ADP16x , it is imperative
that the effects of dc bias, temperature, and tolerances on the
behavior of the capacitors are evaluated for each.
ENABLE FEATURE
ADP160/ADP161/ADP162/ADP163
The start-up behavior of the ADP16x is shown in Figure 39.
The shutdown behavior of the ADP160 / ADP161 is shown in
Figure 40.
3.5
The ADP16x use the EN pin to enable and disable the VOUT
pin under normal operating conditions. As shown in Figure 37,
when a rising voltage on EN crosses the active threshold, VOUT
turns on. When a falling voltage on EN crosses the inactive
threshold, VOUT turns off.

2.5
As shown in Figure 37, the EN pin has hysteresis built in. This
prevents on/off oscillations that can occur due to noise on the
EN pin as it passes through the threshold points.
The EN pin active/inactive thresholds are derived from the VIN
voltage. Therefore, these thresholds vary with changing input

CURRENT LIMIT AND THERMAL OVERLOAD
PROTECTION
The ADP16x are protected against damage due to excessive
power dissipation by current and thermal overload protection
circuits. The ADP16x are designed to current limit when the
output load reaches 320 mA (typical). When the output load
exceeds 320 mA, the output voltage is reduced to maintain a
constant current limit.
Thermal overload protection is included, which limits the junction

conditions (that is, high ambient temperature and power dissipation),
INPUT VOLTAGE (V)
Figure 38. Typical EN Pin Thresholds vs. Input Voltage
when the junction temperature starts to rise above 150°C, the
output is turned off, reducing the output current to zero. When
the junction temperature drops below 135°C, the output is turned
on again and the output current is restored to its nominal value.
