Rohm Electronics (UK) is now offering two new voltage regulators offering dual outputs of either 3.3V and 2.5V or 3.3V and 1.8V, with built-in protection. The BA33C25FP and BA33C18FP two-channel, low-dropout voltage regulators are designed for input voltages between 3V and 16V and maximum currents of 1A. The respective output voltages of 3.3/2.5V and 3.3/1.8V are controlled to within ±2 percent. Suitable for a wide variety of space-limited applications, the new low-dropout-voltage regulators integrate a PNP power transistor with built-in over output current protection circuitry.
The new devices contain an onboard thermal shut-down circuit, which provides protection against thermal breakdown. They come in TO252-5 packaging with dimensions of 6.50 x 5.50 x 2.30mm. Rated operating temperature is between -40 and 85 degrees C, while power dissipation for both devices is 1000mW at 25C.
