80mA Low Noise LDO Voltage Regulator
with Enable Function
Electrical Specification (Continue)
Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The maximum allowable power dissipation at any Ta is Pd(max) = [T_J(MAX) - Ta] + Ó¨_JA. Exceeding the
maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into
thermal shutdown.
Note 3: Devices are ESD sensitive. Handling precautions recommended.
Note 4: The device is not guaranteed to function outside its operating rating.
Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note 6: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
for load regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effects are
covered by the thermal regulation specification.
Note 7: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
Note 8: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn
from the supply is the sum of the load current plus the ground pin current.
Note 9: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation
is applied, excluding load or line regulation effects. Specifications are for a 80mA load pulse at V_IH =16V for
t=10mS.
Application Information
Enable Input
TS5213 series feature an active-high (>2V) enable (EN) input that allows ON/OFF control of the regulator. Current
drain reduces to “zero” when the device is shutdown, with only micro-amperes of leakage current. The EN is
compatible with CMOS logic interfacing. EN may be directly tied to V_IH and pulled up to the maximum supply voltage.
Input Capacitor Requirement
An input capacitor of 0.17uF or greater is recommended when the device is more than 10” away from the bulk AC
supply capacitance or when the supply is a battery.
Output Capacitor Requirement
The TS5213 series requires an output capacitor to maintain stability and improve transient response is necessary.
The TS5213 is ultra stable, requiring only 0.47uF of output capacitance for stability. It is stable with all type of
capacitors, including the tiny, low-ESR ceramic chip capacitors. The output capacitor value may be increased without
limit.
No Load Stability
The TS5213 series will remain stable and in regulation with no load, unlike many other voltage regulators. This is
especially important in CMOS RAM keep alive applications.
