    Looking for -2.5V Output Negative Linear Regulator

    Hi: I am looking for -2.5V fixed Output Negative Linear Regulator. I've tried LM337 to adjust to -2.5V, but it needs precision resistor ratio to get desire voltage. The spec of max1735 seems to meet my requirement. I am wondering if there exists any other choice.
