RT9161 datasheet

 

Description

The RT9161, RT9161A is a 300/500mA fixed output voltage low dropout linear regulator. Typical ground current is approximately 110μA, from zero to maximum loading conditions. Wide range of available output voltage fits most of applications. Built-in output current-limiting most thermal-limiting provide maximal protection against any fault conditions.

For ease of application, the devices comes in the popular 3-pin SOT-23 (300mA), SOT-89 (300mA), SOT-223 (500mA), or TO-92 packages.

Features

1. Input Voltage Range up to 12V
2. Extremely Tight Load Regulation
3. Fast Transient Response
4. Current-limiting and Thermal-limiting

Applications:

1. Voltage Regulator for LAN Card, CD-ROM, and DVD
2. Wireless Communication Systems
3. Battery Powered Systems

APL5505 datasheet

Description

The APL5505 / APL5506 / APL5507 is micropower, low noise , low drop out regulators with a reset function (regulator input (APL5505) or specific voltage(APL5506/7) monitoring), and internal delay circuit, set to detect 3.9V or 4.2V. Operate from 3V to 6V input voltage and deliver up to 500mA. Typical output noise is just 180uVRMSwith an external 0.01uF bypass capacitor connected in BP pin and the typical dropout voltage is only 300mV at 500mA loading. Design with an internal P-channel MOSFET pass transistor, the APL5505/6/7 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and controlled short-circuit current.

Features

• Low Quiescent Current : 120uA (No load)
• Low Dropout Voltage : 300mV (VOUT=3.3V@500mA)
• Stable with 4.7uF Output Capacitor
• Stable with Aluminum , Tantalum or Ceramic Capacitors .
• Reverse Current Protection
• No Protection Diodes Needed
• Built in Thermal Protection
• Built in Current Limit Protection
• Controlled Short Circuit Current : 50mA
• Fast transient Response
• Short Setting Time
• Adjustment-free Reset Detection Voltage : 3.9V or 4.2V typ.
•  Easy to Set Delay Time from Voltage Detection to Reset Release.
•  Reset and Reset output

Applications

• CD-ROM drive.
