FEATURES
GENERAL DESCRIPTION
Constant low RDSON of 40 mΩ over input voltage range
Low input voltage range: 0.9 V to 3.6 V
500 mA continuous operating current at 85°C
1.2 V logic compatible enable input
Low 6 μA quiescent current, independent of load current
Ultralow shutdown current: <100 nA
Ultrasmall 0.8 mm × 0.8 mm × 0.5 mm, 4-ball,
0.4 mm pitch WLCSP
The ADP199 is a high-side load switch designed for operation between 0.9 V to 3.6 V. A load switch provides power
domain isolation, thereby helping to keep subsystems isolated
and powered independently, and enabling reduced power
consumption.
The ADP199 contains a low on-resistance, N-channel MOSFET
to minimize power loss, and supports over 500 mA of continuous
load current. The low 6 μA quiescent current and ultralow
shutdown current make the ADP199 ideal for battery-operated
portable equipment. The built-in level shifter for enable logic
makes the ADP199 compatible with many processors and GPIO
controllers.
APPLICATIONS
Low operating voltage processors
Mobile phones
Digital cameras and audio devices
Portable and battery-powered equipment
Optical XMT/RCVR modules
In addition to high performance, the ADP199 occupies minimal printed circuit board (PCB) space with an area of less than
0.64 mm2 and a height of 0.50 mm.
The ADP199 is available in an ultra-small, 0.8 mm × 0.8 mm ×
0.5 mm, 4-ball, 0.4 mm pitch WLCSP.

ADP199
THEORY OF OPERATION
The ADP199 is a high-side NMOS load switch controlled by
an internal charge pump. The ADP199 is designed to operate
with power supply voltages between 0.9 V and 3.6 V.
An internal charge pump biases the NMOS switch to achieve a
relatively constant, ultralow on resistance of 40 mΩ across the
entire input voltage range. The use of the internal charge pump also
allows for controlled turn-on times. The switch is controlled on/off
by the enable (EN) input and is capable of interfacing directly with
1.2 V logic signals.
The ADP199 is capable of 500 mA of continuous load current
as long as TJ is less than 85°C.
ESD protection structures are shown in the block diagram (see
Figure 29) as Zener diodes.
The ADP199 is a low quiescent current device with a nominal
4 MΩ pull-down resistor on its enable pin (EN). The package is a
space-saving 0.8 mm × 0.8 mm, 4-ball WLCSP.

ENABLE FEATURE
The ADP199 uses the EN input to enable and disable the VOUT
output. As shown in Figure 31, when a rising voltage (VEN) on
the EN pin crosses the active threshold, VOUT turns on. When
a falling voltage (VEN) on the EN pin crosses the inactive
threshold, VOUT turns off.
3.5
VOUT AT 3.3V
3.0
As shown in Figure 31, the EN pin has hysteresis built into it.
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 derive from the VIN voltage;
therefore, these thresholds vary with the changing input voltage.
Figure 33 shows the typical EN active/inactive thresholds when
the input voltage varies from 1.1 V to 3.6 V.

OUTPUT VOLTAGE (V)
The major source for ground current in the ADP199 is the internal
charge pump for the FET drive circuitry. Figure 30 shows the
typical ground current when VEN = VIN, and varies from 1.1 V
to 3.6 V.
Turn-on delay is defined as the interval between the time that
VEN exceeds the rising threshold voltage and when VOUT rises to
~10% of its final value. The ADP199 includes circuitry that has a
typical 1 ms turn-on delay, and a controlled rise time to limit the
VIN inrush current. As shown in Figure 34 and Figure 35, the turnon delay is nearly independent of the input voltage.

Figure 35. Typical Turn-On Delay Time with VIN = 3.6 V,
ILOAD = 10 mA, CLOAD = 1 μF
Figure 37. Typical Rise Time and Inrush Current,
CLOAD = 100 μF, VIN = 3.6 V, ILOAD =100 mA
The rise time is defined as the time it takes the output voltage to
rise from 10% to 90% of VOUT reaching its final value. It is dependent on the rise time of the internal charge pump.
The turn-off time is defined as the time it takes for the output
voltage to fall from 90% to 10% of VOUT reaching its final value.
The turn-off time is also dependent on the RC time constant of
the output capacitance and load resistance. Figure 38 shows the
typical turn-off time with VIN = 1.8 V, COUT = 1 μF, and RLOAD =
18 Ω.
For very large values of output capacitance, the RC time constant
(where C is the load capacitance (CLOAD) and R is the RDSON||RLOAD)
can become a factor in the rise time of the output voltage. Because
RDSON is much smaller than RLOAD, an adequate approximation
for RC is RDSON × CLOAD. An input or load capacitor is not required
for the ADP199 although capacitors can be used to suppress
noise on the board.
