GENERAL DESCRIPTION

The ADP160/ADP161/ADP162/ADP163 are ultralow quiescent

current, low dropout, linear regulators that operate from 2.2 V

to 5.5 V and provide up to 150 mA of output current. The low

195 mV dropout voltage at 150 mA load improves efficiency and

allows operation over a wide input voltage range.

The ADP16x are specifically designed for stable operation with a

tiny 1 µF ± 30% ceramic input and output capacitors to meet

the requirements of high performance, space-constrained

applications.

The ADP160 is available in 15 fixed output voltage options,

ranging from 1.2 V to 4.2 V. The ADP160/ADP161 also include

a switched resistor to discharge the output automatically when

the LDO is disabled. The ADP162 is identical to the ADP160

but does not include the output discharge function.

The ADP161 and ADP163 are available as adjustable output voltage

regulators. They are only available in a 5-lead TSOT package.

The ADP163 is identical to the ADP161 but does not include

the output discharge function.

Short-circuit and thermal overload protection circuits prevent

damage in adverse conditions. The ADP160 and ADP162 are

available in a tiny 5-lead TSOT and a 4-ball, 0.5 mm pitch

WLCSP package for the smallest footprint solution to meet a

variety of portable power applications.

PAGE 13
Data Sheet ADP160/ADP161/ADP162/ADP163 To minimize quiescent current in the ADP161 and ADP163 Analog Devices, Inc., recommends using high values of resistance for R1 and R2. Using a value of 1 MΩ for R2 keeps the total, no load quiescent current below 2 µA. Note however, that high value of resistance introduces a small output voltage error. For example, assuming R1 and R2 are 1 MΩ, the output voltage is 2 V. Taking into account the nominal ADJ pin bias current of 10 nA, the output voltage error is 0.25%.

ADP160/ADP161/ADP162/ADP163 Data Sheet APPLICATIONS INFORMATION CAPACITOR SELECTION Input and Output Capacitor Properties Output Capacitor Any good quality ceramic capacitors can be used with the ADP16x, as long as they meet the minimum capacitance and maximum ESR requirements. Ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior over temperature and applied voltage.
PAGE 15
Data Sheet ADP160/ADP161/ADP162/ADP163 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. The start-up behavior of the ADP16x is shown in Figure 39. The shutdown behavior of the ADP160/ADP161 is shown in Figure 40. ENABLE FEATURE 3.5 4.5 4.0 3.3V 3.0 EN VOLTAGE/VOUT (V) The ADP16x use the EN pin to enable and disable the VOUT pin under normal operating conditions.
PAGE 16
ADP160/ADP161/ADP162/ADP163 Data Sheet THERMAL CONSIDERATIONS In most applications, the ADP16x do not dissipate much heat due to their high efficiency. However, in applications with high ambient temperature and high supply voltage to output voltage differential, the heat dissipated in the package is large enough that it can cause the junction temperature of the die to exceed the maximum junction temperature of 125°C. When the junction temperature exceeds 150°C, the converter enters thermal shutdown.
