Other features include a power good signal when the output is in regulation, precision enable threshold, output
overvoltage protection, thermal shutdown, a temperature monitor, clock synchronization, mode selection and out-
put short circuit protection.
ADP151 - Ultralow Noise, 200 mA, CMOS Linear Regulator
The ADP151 is an ultralow noise, low dropout (LDO) linear regulator that operates from 2.2 V to 5.5 V and pro-
vides up to 200 mA of output current. The low 135 mV dropout voltage at 200 mA load improves efficiency and
allows operation over a wide input voltage range.
Using an innovative circuit topology, the ADP151 achieves ultralow noise performance without the necessity of a
bypass capacitor, making the device ideal for noise-sensitive analog and RF applications. The ADP151 also achieves
ultralow noise performance without compromising the power supply rejection ratio (PSRR) or transient line and
load performance. The low 265 μA of operating supply current at 200 mA load makes the ADP151 suitable for
battery-operated portable equipment.
The ADP151 also includes an internal pull-down resistor on the EN input.
The ADP151 is specifically designed for stable operation with tiny 1 μF, ±30% ceramic input and output capacitors
to meet the requirements of high performance, space constrained applications.
The ADP151 is capable of 16 fixed output voltage options, ranging from 1.1 V to 3.3 V.
Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP151 is availa-
ble in tiny 5-lead TSOT, 6-lead LFCSP, and 4-ball, 0.4 mm pitch, halide-free WLCSP packages for the smallest
footprint solution to meet a variety of portable power application requirements.
STUSB4500 - USB 3.0 Power Delivery
The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algo-
rithm to allow the negotiation of a power delivery contract with a source without MCU support (auto-run mode).
PDO profiles are configured in an integrated non-volatile memory.
The device supports dead battery mode and is suited for sink devices powered from dead battery state and requiring
high power charging profile to be fully operational. Thanks to its 20 V technology, it implements high voltage fea-
tures to protect the CC pins against short-circuits to VBUS up to 22 V and to support high voltage on the VBUS
pins directly connected to the VBUS power path up to 28 V.
