The RP153L Series is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each IC consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. These ICs have low dropout voltage due to a built-in transistor with low ON resistance, and the chip enable function extends the battery life of each system. The line transient response and load transient response of the RP153L Series are excellent, making them very suitable for power supply in handheld communication equipment. The output voltage of these ICs is internally fixed with high accuracy. The ICs are packaged in DFN1216-8, allowing for high-density mounting on boards. In RP153L, the power supply of each circuit can be individually supplied. The transient response characteristic of the D and E versions has been improved.
The RP153L Series consists of CMOS-based voltage regulator ICs featuring high output voltage accuracy, low supply current, and low dropout. Each package contains two regulators with individually supplied power circuits, making them suitable for high-density mounting on boards.
Key features include a typical supply current of 40µA per channel (D/E versions), excellent ripple rejection of 70dB at 1kHz, and an output voltage accuracy of ±1.0%. The ICs are housed in a DFN1216-8 package and operate within a temperature range of -40°C to +85°C.
