BCT2193
Low Power, Low Dropout, RF-Linear Regulators
GENERAL DESCRIPTION
The BCT2193 series low-power, low-dropout, CMOS linear voltage regulators operate from a 1.6V to 5.5V input voltage and deliver up to 300mA output current. They are the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The BCT2193 series also offer low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the BCT2193 series’ low output noise and high PSRR.
Other features include a 10nA logic-controlled shutdown mode, short current limit and thermal shutdown protection.
The BCT2193 has auto-discharge function to quickly discharge VOUT in the disable status. The BCT2193 is available in Green SOT23-3 , SOT89-3 packages. It operates over an ambient temperature range of -40℃ to +85℃.
