3340 negative supply

[Tony Allgood]

Hi all,

Anyone know how much a 3340 draws from the negative rail when powered
off exactly -5V? That is no zener conduction. Its not on the data sheet,
but the positive rail is listed at about 7mA. I could measure it, but I
thought maybe someone already knows. I think I will use a compensated
5534 to drive it, as I only have two 3340s to power.
