HT93LC66 - CMOS 4K 3-Wire Serial EEPROM

General Description
The RT9004 is designed for portable RF and wireless applications with demanding performance and space requirements.
The RT9004 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current.
Regulator ground current increases only slightly in dropout, further prolonging the battery life.
The RT9004 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
The RT9004 consumes less than 0.01uA in shutdown mode and has fast turn-on time less than 50us.
RT9004 is short circuit thermal folded back protected.
RT9004 lowers its OTP trip point from 165°C to 110°C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users.
The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
Available in the VDFN-10L 3x3 and WDFN-10L 3x3 packages, the RT9004 also offers custom voltage, range of 1.5V to 3.5V with 0.1V per step.

RT9004 - 300mA, Low Noise, Ultra-Fast CMOS Triple LDOs Regulator

General Description
AP5004 consists of step-down switching regulator with PWM control.
These devices include a reference voltage source, oscillation circuit, error amplifier, internal NMOS.
AP5004 provides low-ripple power, high efficiency and excellent transient characteristics.
The PWM control circuit is able to vary the duty ratio linearly from 0 up to 90%.
An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 300 KHz to 50 KHz.
Also, an internal compensation block is built to minimize external component count.
With built-in power NMOS, a step-down switching regulator is easy to be built by adding a coil, capacitors and a diode.
The high efficiency, low standby current, high input voltage (32V) and output current (2.5A) combining with small SOP-8L package give AP5004 unprecedented advantage in high power system applications.

Features
* Input Voltage: 10V to 32V
* Adjustable Output Voltage from 0.8V to 6V
* Duty Ratio: 0% to 90% PWM control
* Oscillation Frequency: 300KHz typical
* Short Circuit Protect Frequency:50 KHz
* 2uA Maximum Standby Current
* Current Limit, Enable Function
* Thermal Shutdown Function
* Built-in Internal SW N-channel MOS
* SOP-8L: Available in “Green” Molding Compound (No Br, Sb)
* Lead Free Finish/RoHS Compliant (Note 1)

Applications
* Microprocessor Core Supply
* Networking Power Supply
* LCD MNT, TV Power Supply
* Telecom Power Supply
